The space integration of the lithiation of aryl halides, the borylation of aryllithiums, and Suzuki-Miyaura coupling using a Pd catalyst supported by a polymer monolith flow reactor without using an intentionally added base was achieved. To scale up the process, a series connection of the monolith Pd reactor was examined. To suppress the increase in the pressure drop caused by the series connection, a monolith reactor having larger pore sizes was developed by varying the temperature of the monolith preparation. The monolithic Pd reactor having larger pore sizes enabled Suzuki-Miyaura coupling at a higher flow rate because of a lower pressure drop and, therefore, an increase in productivity. The present study indicates that series connection of the reactors with a higher flow rate serves as a good method for increasing the productivity without decreasing the yields.

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.

Newly designed dimethylamine-substituted triphenylamine (TPA) derivatives, N,N’-(1,4-phenylene)bis(N-(4-((tert-butyldimethylsilyl)oxy)phenyl)-N ”,N ”-dimethylbenzene-1,4-diamine) (NTPPA-2Si) and N,N’4(1,1′-biphenyl)-4,4′-diyl)bis(N-(4-((tert-butyldimethylsilyl)oxy)pheny1)-N ”,N ”-dimethylbenzene-1,4-diamine) (NTPB-2Si), with silyl ether protecting groups were readily synthesized. Subsequently, novel electroactive aromatic poly(ether sulfone)s (PES), NTPPA-PES and NTPB-PES, could be obtained from silyl polycondensation. The PESs were readily soluble in commonly used laboratory organic solvents and could be solution-cast into tough and amorphous films with moderate levels of glass-transition temperature around 220 degrees C and thermal stability without significant weight loss up to 400 degrees C under nitrogen or air atmosphere. The Nernst equation method was used to explore the number of electrons transferred at each oxidation step of the targeted two monomers. Furthermore, these two anodic electrochromic PESs were introduced into electrochromic devices accompanied with cathodic heptyl viologen (HV), and the resulted devices demonstrated a high coloration contrast and excellent electrochemical stability.

This paper describes the facile synthesis of haloaryl compounds with long-chain alkanoyl substituents by the destannylative acylation of haloaryls bearing tri-n-butyltin (Bu3Sn) substituents. The method allows the synthesis of many important synthons for novel functional materials in a highly efficient manner. The halo-tri-n-butyltin benzenes are obtained by the lithium-halogen exchange of commercially available bis-haloarenes and the subsequent reaction with Bu3SnCl. Under typical Friedel-Crafts conditions, i.e., the presence of an acid chloride and AlCl3, the haloaryls are acylated through destannylation. The reactions proceed fast (<5 min) at low temperatures and thus are compatible with aromatic halogen substituents. Furthermore, the method is applicable to para-, meta-, and ortho-substitution and larger systems, as demonstrated for biphenyls. The generated tin byproducts were efficiently removed by trapping with silica/KF filtration, and most long-chain haloaryls were obtained chromatography-free. Molecular structures of several products were determined by X-ray single-crystal diffraction, and the crystal packing was investigated by mapping Hirshfeld surfaces onto individual molecules. A feasible reaction mechanism for the destannylative acylation reaction is proposed and supported through density functional theory (DFT) calculations. DFT results in combination with NMR-scale control experiments unambiguously demonstrate the importance of the tin substituent as a leaving group, which enables the acylation.

Carbon-nitrogen (C-N) bond-forming cross-coupling reactions catalyzed by palladium-based catalysts, the so-called Buchwald-Hartwig aminations, have been widely employed for the synthesis of pharmaceuticals and aryl-amine-based organic materials in academic and industrial settings. However, in solution, these reactions usually require glovebox and Schlenk line techniques, which greatly reduces their practical utility. Here, we report the development of operationally simple mechanochemical C-N cross-coupling reactions in the solid-state. Intensive investigations of various ball milling parameters revealed that the air-stable ligand tri(1-adamantyl)phosphine can be used to achieve solid-state coupling reactions between aryl halides and diarylamines with high efficiency. Notably, all experimental operations of the developed protocol can be carried out in air, thus providing a more convenient, industrially attractive, and sustainable alternative to conventional solution-based palladium-catalyzed C-N coupling reactions.

A deep-blue thermally activated delayed fluorescence (TADF) emitter TXADO-spiro-DMACF has been reported for nondoped organic light-emitting diodes (OLEDs) by integrating an appropriate blocking unit with the donor (D)-acceptor (A)-donor (D)-type TADF emitter via a spiro linkage. Benefiting from the characteristic perpendicular arrangement, the intermolecular interactions are expected to be weakened to some degree. As a result, TXADO-spiro-DMACF shows a very small bathochromic shift of 8 nm associated with a narrowed full width at half maximum of 54 nm on going from solution to the film. The corresponding nondoped device successfully achieves a bright deep-blue emission, revealing Commission Internationale de l’Eclairage coordinates of (0.16, 0.09) and a peak external quantum efficiency of 5.3% (5.3 cd/A, 5.9 lm/W). The results clearly indicate that spiro-blocking is a promising strategy to develop deep-blue TADF emitters capable of nondoped OLEDs.

An electroactive polytriphenylamine (PTPA-C6) is blended with poly(styrene-co-hydroxystyrene) (PS-co-PHS) as coating layers to enhance protection efficiency of PTPA-C6 on iron substrate in 3.5% sodium chloride (NaCl) solution. Experimental results show that incorporation of hydroxyl group to the polystyrene not only increases the miscibility of PTPA-C6 with PS through the hydrogen bond formation, but also enhances the bonding strength between the polymer coating layer and iron substrate. These improvements lead to superior enhancement in anticorrosion performance of PTPA-C6, even after thermal treatment. Protection efficiency (PE) of PTPA-C6 increases from 81.52% of the PTPA-C6 itself to over 94.40% under different conditions (PEmax = 99.19%).

A palladium catalysed Ullmann biaryl synthesis has been developed using hydrazine hydrate as the reducing reagent at room temperature. The combination of Pd(OAc)(2) and hydrazine hydrate works smoothly for the coupling of both electron-rich and electron-deficient aryl iodides, as well as hetero-aryl iodides, leading to a wide range of biaryls in good to excellent yields. The reaction requires only 1 mol% Pd(OAc)(2) and the in situ generated palladium naoparticles are found to be active catalysts.

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.
