Porous metal-organic frameworks (MOFs) have excellent characteristics for the adsorptive removal of environmental pollutants. Herein, we introduce a new series of highly stable MOFs constructed using Fe3+ and Al3+ metal ions and bisphosphinate linkers. The isoreticular design leads to ICR-2, ICR-6, and ICR-7 MOFs with a honeycomb arrangement of linear pores, surface areas up to 1360 m(2) g(-1), and high solvothermal stabilities. In most cases, their sorption capacity is retained even after 24 h of reflux in water. The choice of the linkers allows for fine-tuning of the pore sizes and the chemical nature of the pores. This feature can be utilized for the optimization of host-guest interactions between molecules and the pore walls. Water pollution by various endocrine disrupting chemicals has been considered a global threat to public health. In this work, we prove that the chemical stability and hydrophobic nature of the synthesized series of MOFs result in the remarkable sorption properties of these materials for endocrine disruptor bisphenol A.

Two new M8L4 tetrafacial nanotubes (T1 and T3) of different lengths have been synthesized in water using ligands L1 and L2, respectively, with acceptor cis-[(dch)Pt(NO3)(2)] (M) using coordination-driven self-assembly [where dch is 1,2-diaminocyclohexane, L1 is 1,4-di(pyrimidin-5-yl)benzene, and L2 is 4,4′- di(pyrimidin-5-yl)-1,1′-biphenyl]. In addition to complex T1, a tetrahedral cage of composition [M-12(L1)(6)] (T2) was also formed in the self-assembly reaction of ligand L1 with cis-[(dch)Pt(NO3)(2)]. The precise composition of the products (T1 and T2) in solution was confirmed by H-1 NMR and ESI-MS. Pure tube T1 was separated out by a crystallization technique and fully characterized by 1H NMR and X-ray diffraction. Temperature- and concentration-dependent NMR studies indicated no equilibrium between T1 and T2 in the solution phase, and the proportion of T1 and T2 in the mixture depends on the temperature of the reaction. In contrast to ligand L1, the self-assembly of the longer ligand, L2, with cis-[(dch)Pt(NO3)(2)] gave only tetrafacial tube [M-8(L-2)(4)] (T3) without any tetrahedral cage.

A facile and less expensive hole transport material is essential to enhance the power conversion efficiency (PCE) of perovskite solar cells (PSC) without compromising the ambient stability. Here, we designed and synthesized a new class of HTM by introducing donor-pi-acceptor (D-pi-A). The HTM was synthesized by combining the moieties of triphenylamine, biphenyl and oxadiazole derivatives as electron donating, pi-spacer and electron withdrawing moieties, respectively, named 4 ”’-(5-(4-(hexyloxy)phenyl)-1,3,4-oxadiazol-2-yl)-N,N-bis(4-methoxyphenyl)-[1,1′:4′,1 ”:4 ”,1 ”’-quaterphenyl]-4-amine (TPA-BP-OXD). The pi-pi conjugation is increased by introducing the biphenyl pi-spacer. The HTM was terminated with an OXD-based moiety and framed as a D-pi-A-based HTM that trigged improvement in the charge transportation properties due to its pi-pi interactions. We rationally investigated the HTM by characterizing its photophysical, thermal, electrochemical, and charge transport properties. The great features of the HTM stimulated us to explore it on rigid and flexible substrates as a dopant-free HTM in planar inverted-perovskite solar cells (i-PSCs). The device performance in solution processed dopant-free HTM based i-PSC devices on both rigid and flexible substrates showed PCEs of 15.46% and 12.90%, respectively. The hysteresis is negligible, which is one of the most effective results based on a TPA-BP-OXD HTM in planar i-PSCs. The device performance and stability based on the TPA-BP-OXD HTM are better due to higher extraction and transportation of holes from the perovskite material, reduced charge recombination at the interface, and enhanced hydrophobicity of the HTM to compete for a role in enhancing the stability. Overall, our findings demonstrate the potentiality of the TPA-BP-OXD based HTM in planar i-PSCs.

An article In search of efficient solubilizing groups for liquid and luminescent oligo(phenylene-thiophene) chromophores WOS:000600128000045 published article about CHARGE-TRANSPORT; UP-CONVERSION; EMISSION; DYES in [Luponosov, Yuriy N.; Balakirev, Dmitry O.; Dyadishchev, Ivan, V; Solodukhin, Alexander N.; Obrezkova, Marina A.; Svidchenko, Evgeniya A.; Surin, Nikolay M.; Ponomarenko, Sergey A.] Russian Acad Sci, Enikolopov Inst Synthet Polymer Mat, Prafsoyuznaya St 70, Moscow 117393, Russia in 2020, Cited 45.

In this work, the synthesis of oligomers having a rigid conjugated 4,4 ‘-bis(2-thienyl)biphenyl fragment end-capped with various types of solubilizing groups (SGs), such as either alkyl or alkylsilyl or alkyl-oligodimethylsiloxane, has been reported. The comprehensive study of their thermal and optical properties as well as rheology in comparison to model highly crystalline oligomers with simple either hexyl or trimethylsilyl SGs allowed us to elucidate structure-property correlations and find the most powerful type of SG in terms of liquefaction for them. It was revealed that oligomers with long and branched alkyl SGs still retain high crystallinity, whereas oligomers with alkyl-oligodimethylsiloxane SGs combine very low glass transition temperatures (up to -111 degrees C) with a liquid-crystalline behaviour. The alkylsilyl SGs were found to be the most efficient, since the oligomers end-capped with trihexyl- and tri(2-butyloctyl)silyl SGs are liquid and have low values of both the glass transition temperature (up to -60 degrees C) and viscosity (up to 1.94 Pa s). All the oligomers prepared have similar optical absorption/luminescence spectra and high values of photoluminescence quantum yield in solution (90-95%) without a significant impact of the SG type. In the neat films, the type of SG has a huge impact on the shape and maxima of the absorption and luminescence spectra as well as the photoluminescence efficiency. Among this series of molecules, oligomers with alkylsilyl SGs demonstrate the highest values of photoluminescence quantum yield in the neat form (24-61%) and close to the solution optical characteristics, which indicates their strong capability to suppress aggregation of molecules in the bulk. Thus, for the first time liquid luminescent thiophene/phenylene co-oligomers were reported and the solubilizing capabilities of some of the most promising types of SG were comprehensively investigated and compared to each other. The results obtained can be used as a guideline for the design of functional materials based on conjugated oligomers with a tunable and controllable phase behaviour, solubility and optical properties in the neat state.

Developing efficient and wide spectrally acting photocatalysts for light-driven hydrogen production from water is highly desirable for solar energy conversion. Herein, diketopyrrolopyrrole (DPP) is used to combine with triphenylamine (TPA), bipyridyl (bdy), and biphenyl (bph) units for construction of conjugated microporous polymer photocatalysts. Although the synthesized two polymers, DPP-bdy-TPA and DPP-bph-TPA, have a similar framework structure, the former bearing a hydrophilic , bipyridyl unit displays much better photocatalytic performance with hydrogen production rates of 6918 and 2780 mu mol g(-1) h(-1) under a full-arc xenon lamp and visible light (>440 nm) illumination, respectively. Moreover, DPP-bdy-TPA has a wide photoaction spectrum with apparent quantum yields of 9.60% at 420 nm, 7.32% at 500 nm, and 0.31% at 600 nm, the so high values rarely achieved by present-known organic semiconductor photocatalysts. These results undoubtedly prove DPP is an excellent building block, and this work well exemplifies its utilization for construction of high-performance photocatalysts.

A nickel-catalyzed cross-electrophile coupling reaction between (hetero)aryl bromides and 2,2-difluorovinyl tosylate is presented. This protocol provides facile incorporation of the gem-difluorovinyl moiety in organic molecules. The method features mild reaction conditions, good functional group tolerance, and excellent yields. Furthermore, mechanistic experiments and DFT studies indicate a Ni(0)/Ni(II) catalytic cycle, thus differing from the currently accepted catalytic cycle for nickel-catalyzed C(sp(2))-C(sp(2)) cross-electrophile coupling reactions.

Yamamoto coupling polymerization has been used for the synthesis of polymeric chiral organocatalysts. Cinchona squaramide derivatives with dibromophenyl moiety were polymerized under the Yamamoto coupling conditions to afford the corresponding chiral polymers in good yields. Using this technique, novel cinchona alkaloid polymers containing the squaramide moiety were designed and successfully synthesized. In addition to the homopolymerization of cinchona squaramide monomers with a dibromophenyl group, achiral comonomers such as dibromobenzene were copolymerized with the cinchona monomers to yield chiral copolymers. These chiral polymers were successfully utilized as polymeric catalysts in asymmetric Michael addition reactions. Good to excellent enantioselectivities were observed for different types of asymmetric Michael reactions. Using the chiral homopolymer catalyst P4, almost perfect diastereoselectivity (>100:1) with 99% ee was obtained for the reaction between methyl 2-oxocyclopentanecarboxylate 25 and trans-beta-nitrostyrene 17. The polymer catalysts developed in this study have robust structures and can be reused several times without a loss in their catalytic activities.

The present work demonstrates the operation of a reversible supramolecular gate, i.e., an ensemble of various components linked by chemical communication, which is triggered by stoichiometric chemical inputs and by obeying the AND truth table delivers a stoichiometric chemical signal. The output triggers a series of events that finally set up a catalytic process. In detail, a three-component AND gate, composed of two distinct nanoswitches, a copper-loaded and an unloaded one {= state (0,0)}, was actuated with stoichiometric amounts of two inputs (IN-1 = Zn2+, IN-2 = Hg2+) generating copper(I) ions as output in state (1,1). The utility of this information processing was highlighted by using the copper(I) output for triggering the self-assembly of the four-component rotor ROT-2 through metal translocation. In the presence of suitable reactants, ROT-2 acted as a catalytic machinery catalyzing a click reaction (= signal amplification). Verification of the functioning of the AND gate in a mixture of 12 components was thus accomplished by monitoring formation of the click product. Due to the stoichiometric design, the gate was reset to state (0,0) by adding hexacyclen and reactivated by adding inputs IN-1 and IN-2 alike in the first cycle.

A pre-formed catalyst Pd2+/PANI composite for C-C coupling reaction was synthesized by combining the self-stabilized dispersion polymerization method with the in-situ composite material. Experiments have confirmed that the relatively high reduced structure (75%) in the polyaniline carrier is more favorable for the coupling reaction. Raman spectroscopy, solid nuclear magnetic, and X-ray photoelectron spectroscopy were performed to characterize the structures. The pre-formed catalyst has uniform coordination of divalent palladium and nitrogen in different valence states of the carrier polyaniline, which shows a good synergistic effect in the catalytic Ullmann reaction, and greatly reduces the use of reducing agents such as hydrazine hydrate. Compared with other studies, we analyzed the catalytic reaction mechanism in detail through real-time online infrared and XPS characterization. The results show that the divalent palladium in the catalyst and the zero-valent palladium generated by the in-situ reaction synergistically promote the reaction, while the polyaniline support acts as a stabilizer and dispersant, which prevents the agglomeration of the metal particles and prolongs increased catalyst life. The prepared Pd2+/PANI composites will become the most attractive alternative to traditional organic materials due to their wide applicability, high catalytic activity, stable recycling and relatively low price. This work provides a new theoretical basis for the understanding of the essential driving force of PANI catalytic activity and the cognition of the micro mechanism of action. (C) 2020 Elsevier Inc.

Many interesting target guest molecules have low symmetry, yet most methods for synthesising hosts result in highly symmetrical capsules. Methods of generating lower symmetry pores are thus required to maximise the binding affinity in host-guest complexes. Herein, we use mixtures of tetraaldehyde building blocks with cyclohexanediamine to access low-symmetry imine cages. Whether a low-energy cage is isolated can be correctly predicted from the thermodynamic preference observed in computational models. The stability of the observed structures depends on the geometrical match of the aldehyde building blocks. One bent aldehyde stands out as unable to assemble into high-symmetry cages-and the same aldehyde generates low-symmetry socially self-sorted cages when combined with a linear aldehyde. We exploit this finding to synthesise a family of low-symmetry cages containing heteroatoms, illustrating that pores of varying geometries and surface chemistries may be reliably accessed through computational prediction and self-sorting.
