Thiele, Chichibabin and Muller hydrocarbons are considered as classical Kekule diradicaloids. Herein we report the synthesis and characterization of acyclic diaminocarbene (ADC)-based Thiele, Chichibabin, and Muller hydrocarbons. The calculated singlet-triplet energy gaps are Delta ES-T = -27.96, -3.70, -0.37 kcal mol(-1), respectively, and gradually decrease with the increasing length of the pi-conjugated spacer (p-phenylene vs. p,p ‘-biphenylene vs. p,p ”-terphenylene) between the two ADC-scaffolds. In agreement with the calculations, we also experimentally observed the enhancement of paramagnetic diradical character as a function of the length of the pi-conjugated spacer. ADC-based Thiele’s hydrocarbon is EPR silent and exhibits very well resolved NMR spectra, whereas ADC-based Muller’s hydrocarbon displays EPR signals and featureless NMR spectra at room temperature. The spacer also has a strong influence on the UV-Vis-NIR spectra of these compounds. Considering that our methodology is modular, these results provide a convenient platform for the synthesis of an electronically modified new class of carbon-centered Kekule diradicaloids.

The long-range migration ability of persistent organic pollutants was characterized by both K-OA and P-L. It is difficult for a traditional model of 3D-QSAR to capture the relationship between the double activities of pollutants and their structures. To this end, a log-normalized method was employed to treat a given data set (K-OA and P-L values) to obtain a comprehensive activity (Z) that represents the long-range migration ability of polyhalogenated biphenyls. Then, the relationship between the comprehensive activity of polyhalogenated biphenyls and their structures could be constructed; the proposed model was named the three-dimensional quantitative structure-double-activities relationship (3D-QSA(2)R) model. Two new PCB-52 molecules with a reduced ability for long-range migration were designed after analyses of the contour maps, with Z values increasing significantly by 30.44-41.30%, and the environmental persistence, bioconcentration and biotoxicity decreased by 3.37-8.99%, 26.86-26.73% and -1.17-3.50%, respectively, compared with those of PCB-52. logK(OA) and logP(L) values of the novel modified PCB-52 were predicted as 3.20-4.57% and 74.57-79.19%, respectively, by the EPI database software, and these values showed a consistent increasing trend with the Z values predicted by 3D-QSA(2)R, indicating that the established 3D-QSA(2)R could be used to deal with the relationship between the multi-activities of organic pollutants and their structures.

A microwave-assisted, efficient and rapid Sonogashira reaction was developed for the synthesis of polysubstituted aromatic alkynes. The reaction was made environmentally friendly and easy to perform by replacing the traditional amine solvents with water. The optimized reaction conditions yielded the products with high yields, while reducing the dependence on anaerobic reaction conditions with no inert gas protection. The reaction also achieved the product on the milligram level, overcoming the problem of TMSA volatilization in small-scale reactions. The environmentally friendly reaction solvent, mild reaction conditions, high reaction yields and short reaction time made the reaction highly promising for various applications, especially for synthesizing porous aromatic frameworks.

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.

Polyelectrolytes play an important role in both natural biological systems and human society, and their synthesis, functional exploration, and profound application are thus essential for biomimicry and creating new materials. In this study, we developed an efficient synthetic methodology for in situ generation of azonia-containing polyelectrolytes in a one-pot manner by using readily accessible nonionic reactant in the presence of commercially available cheap ionic species. The resulting polyelectrolytes are emissive in the solid state and can readily form luminescent photopatterns with different colors. The azonia-containing polyelectrolytes possess extraordinary potency of reactive oxygen species (ROS) generation, enabling them to impressively kill methicillin-resistant Staphylococcus aureus (MRSA), a drug resistant superbug, both in vitro and in vivo.

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.

This study intends to design and prepare a new magnetic copper catalyst and its activity was assessed by carbon-carbon coupling reactions. For this purpose, 1-[3-(trimethoxysilyl) propyl] urea (TMSPU), hydrazine and CuI were used sequentially to modify Fe3O4@SiO2 core-shell magnetic nanoparticles to obtain an efficient magnetic transition metal catalyst. Various analytical techniques were used to characterize the catalyst to show that the achieved structure and its properties are well-suited for coupling reactions. Finally, Mizoroki-Heck and Ullmann coupling reactions were performed using Fe3O4@SiO2@PrNCu catalyst. The new catalyst offer simple synthetic procedure, convenient use for routine casework and low price. The Fe3O4@SiO2@PrNCu catalyst was easily separated by means of a permanent and ordinary magnet and the recovered catalyst was reused in six cycles without any significant loss of activity.

Airborne particulate matter (PM) has received increasing attention as it causes serious environmental pollution and huge health risk for humans. Herein, we demonstrate the synthesis of tubular conjugated microporous polymers (CMPs) via a one-step cross-coupling reaction for the removal of PM from the air. Tubular CMPs possess a large specific surface area (>484 m(2) g(-1)), high physicochemical stability and mechanical flexibility and robustness. Benefiting from their abundant porosity, CMP-based filters show desirable ability for the capture of PM with a high efficiency of greater than 99% for both PM2.5 and PM10. In combination with their interestingly intrinsic hydrophobicity, a high filtration efficiency for PM2.5 greater than 99.97% can be obtained even under high-humidity conditions (relatively 96 +/- 2%), which can be maintained unchanged during a 12 h continuous test, making them highly advantageous over those hydrophilic filters that usually lose their filtration efficiency in a humid environment. Based on their simple fabrication, inherently hydrophobic wettability and high filtration efficiency, the as-synthesized CMP-based filters would hold great potential as promising filters for PM elimination in a humid environment under harsh conditions by taking the advantage of the intrinsically robust physicochemical properties of CMPs. More interestingly, due to the designable flexibility of CMPs, which makes it possible for fine-tuning their pore size or chemical composition, the tailored-design of advanced CMP-based filters for a specific purpose could be anticipated only by rationally varying the size or structure of their building blocks.
