Organic pi-conjugated polymers (CPs) have been intensively explored for a variety of critical photocatalytic applications in the past few years. Nevertheless, CPs for efficient CO2 photoreduction have been rarely reported, which is mainly due to the lack of suitable polymers with sufficient solar light harvesting ability, appropriate energy level alignment and good activity and selectivity in multi-electron-transfer photoreduction of CO2 reaction. We report here the rational design and synthesis of two novel triphenylamine (TPA) based conjugated microporous polymers (CMPs), which can efficiently catalyze the reduction of CO2 to CO using water vapor as an electron donor under ambient conditions without adding any co-catalyst. Nearly 100% selectivity and a high CO production rate of 37.15 mu mol h(-1) g(-1) are obtained for OXD-TPA, which is significantly better than that for BP-TPA (0.9 mu mol h(-1) g(-1)) as a result of co-monomer change from biphenyl to 2,5-diphenyl-1,3,4-oxadiazole. This difference could be mainly ascribed to the synergistic effect of a decreased optical band gap, improved interface charge transfer and increased CO2 uptake for OXD-TPA. This contribution is expected to spur further interest in the rational design of porous conjugated polymers for CO2 photoreduction.

A novel family of N-heterocyclic carbene (NHC)-incorporated Se-Fe-Cu compounds, bis-1,3-dimethylimidazol-2-ylidene (bis-Me-2-imy)-containing compound [(mu(4)-Se)Fe-3(CO)(9){Cu(Me-2-imy)}(2)] (2), bis-N-methyl- or bis-N-isopropyl-substituted benzimidazol-2-ylidene (bis-Me-2-bimy or bis-Pr-i(2)-bimy)-incorporated compounds [(mu(4)-Se)Fe-3(CO)(9){Cu(Me-2-bimy)}(2)] (3) or [(mu(4)-Se)Fe-3(CO)(9){Cu(Pr-i(2)-bimy)}(2)] (4), and a bis-1,3-dimethyl-4,5-dichloroimidazol-2-ylidene (bis-Me-2-Cl-2-imy)-containing compound [(mu(3)-Se)Fe-3(CO)(9){Cu(Me-2-Cl-2-imy)}(2)] (5), were synthesized in moderate yields in facile one-pot reactions of the ternary pre-designed compound [(mu(3)-Se)Fe-3(CO)(9){Cu(MeCN)}(2)] (1) with the corresponding imidazolium salts and (KOBu)-Bu-t in THF in an ice-water bath. Single-crystal X-ray analyses revealed that the Me-2-imy compound 2 or the Me-2-bimy compound 3 each exhibited a trigonal bipyramidal SeFe3(CO)(9)Cu geometry with an Fe2Cu plane further capped by a Cu(Me-2-imy) or Cu(Me-2-bimy) fragment, respectively, with one long Cu-Cu covalent bond. In addition, compound 4 also comprised a trigonal bipyramidal SeFe3(CO)(9)Cu core structure, but the second Cu(Pr-i(2)-bimy) group bridged the equatorial Fe-Fe edge with two unbonded Cu atoms, due to the presence of a sterically bulky Pr-i(2)-bimy fragment. On the other hand, the strong electron-withdrawing chloro-containing NHC compound 5 showed a comparatively open tetrahedral SeFe3(CO)(9) metal core, where two Fe-Fe edges each were further bridged by a Cu(Me-2-Cl-2-imy) fragment. Due to the nonclassical C-H center dot center dot center dot O(carbonyl) hydrogen bonds between the CO groups of the SeFe3(CO)(9)Cu-2 core and CH moieties of the neighboring NHC ligands, both compounds 2 and 3 comprised a one-dimensional network, while compounds 4 and 5 each were made up of a two-dimensional framework in the solid state, which efficiently enhanced the stability of these Se-Fe-Cu NHC compounds. Importantly, all of these synthesized Se-Fe-Cu NHC compounds 2-5 had pronounced catalytic activities for the homocoupling of arylboronic acids with high catalytic yields. Finally, these Se-containing Fe-Cu NHC compounds further represented excellent models for studying chalcogen effects in comparison to their Te analogs, as demonstrated by their catalytic performances and electrochemical behaviors, and by DFT calculations.

A series of tetracationic quadrupolar chromophores containing three-coordinate boron p-acceptors linked by different p-bridges, namely 4,4′-biphenyl, 2,7-pyrene, 2,7-fluorene, 3,6-carbazole and 5,5′-di(thien-2yl)- 3,6-diketopyrrolopyrrole, were synthesized. While their neutral precursors 1-5 displayed highly solvatochromic fluorescence, the water-soluble tetracationic target molecules 1M-5M, did not, but their emission colour could be tuned from blue to pink by changing the p-bridge. Compound 5M, containing the diketopyrrolopyrrole bridge, exhibits the most red-shifted absorption and emission maxima and the largest two-photon absorption cross-section (4560 GM at 740 nm in MeCN). Confocal laser scanning fluorescence microscopy studies in live cells confirm localization of the dye at the lysosome. Moreover, the low cytotoxicity, and high photostability of 5M combined with two-photon excited fluorescence imaging studies demonstrate its excellent potential for lysosomal imaging in live cells.

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.

In this work, a series of novel luminescent molecules of butterfly-like architecture based on TPA fragments with different central and side aromatic blocks were designed and synthesized. Various properties of the molecules were studied by differential scanning calorimetry, thermogravimetric analysis, UV-Vis optical spectroscopy and compared within this series as well as to their analogs having terminal trimethylsilyl moieties instead of diphenylamine ones. The molecules reported are promising luminescent materials, which combine high thermal stability, good solubility and large molar extinction coefficients with high photoluminescence quantum yields for emission in the green and red spectral regions. The experimental and theoretical investigations reported give more insight to the structure – property correlations for the TPA-based luminophores, as well as to their photostability and peculiarities of the conjugation through triphenylamine units between the central and the side fragments.

Radical cations of bis(dianisylamino)-terminated oligo(p-phenylene)s (OPPs) with up to five phenyl moieties were characterized by means of UV/Vis-NIR and variable-temperature ESR spectroscopy to investigate the bridge-length-dependence on intramolecular charge/spin self-exchange between two nitrogen redox-active centers. Additionally, a comparative study between bis(dianisylamine)-based mixed-valence (MV) radical cations connected by p-terphenylene and hexa-peri-hexabenzocoronene (HBC) pi-bridging units also provided information on the influence of extended pi-conjugation over the OPP-bridge due to the planarization between adjacent phenylene units on the strength of electronic coupling. The present study on a homologous series of organic MV systems clarifies the attenuation factor through the OPP-bridge and the linear relationship between the electrochemical potential splitting and the electronic coupling in the region of intermediate-to-weak electronic coupling regime.

Reported here is a molecule-Lego synthetic strategy for macrocycles with functional skeletons, involving one-pot and high-yielding condensation between bis(2,4-dimethoxyphenyl)arene monomers and paraformaldehyde. By changing the blocks, variously functional units (naphthalene, pyrene, anthraquinone, porphyrin, etc.) can be conveniently introduced into the backbone of macrocycles. Interestingly, the macrocyclization can be tuned by the geometrical configuration of monomeric blocks. Linear (180 degrees) monomer yield cyclic trimers and pentamers, while V-shaped (120 degrees, 90 degrees and 60 degrees) monomers tend to form dimers. More significantly, even heterogeneous macrocycles are obtained in moderate yield by co-oligomerization of different monomers. This series of macrocycles have the potential to be prosperous in the near future.

In this work, polymers comprising of the different ratios of N-decyl or N-triethylene glycol substituted 2,7-carbazoles and tetraphenylethenes were designed and synthesized by palladium-catalyzed Suzuki Miyaura cross coupling reaction of their corresponding comonomers. The copolymers containing carbazoles and tetraphenylethenes showed aggregation induced emission characteristics in both solid state and aggregate state when the composition of the tetraphenylethenes reached to 50%. N-triethylene glycol substituted carbazole polymers revealed lower bandgap and higher HOMO level compared to that of the N-decyl substituted carbazole polymers. The higher composition of the tetraphenylethenes, the deeper HOMO level and the larger bandgap of the polymers. Polymers with 1:1 molar ratio of the carbazoles and the tetraphenylethenes exhibited sphere-like nanoparticles with an average diameter of around 30 nm. The polymers containing carbazole and TPE units in 3:1 or 1:3 molar ratio self-assembled to form nanoaggregates with a size of around 100 nm.

Symmetrical and unsymmetrical biaryls comprises a diverse class of biologically eloquent organic compounds. We herein report, a quick and eco-friendly protocol for the synthesis of biaryls by an oxidative (aerobic) homocoupling of arylboronic acids (ABAs) using Pd(OAc)(2) in water extract of pomogranate ash (WEPA) as an efficient agro-waste(bio)-derived aqueous (basic) media. The reactions were executed at ambient aerobic conditions in the absence of external base and ligand to result symmetrical biaryls in excellent yields. The use of renewable media with an effective exploitation of waste, short reaction times, excellent yields of products, easy separation of the products, unnecessating the external base, oxidant, ligand or volatile organic solvents and ambient reaction conditions are the vital insights of the present protocol.
