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.

Three cost-effective D-pi-D hole transport materials (HTMs) with different pi-bridges, including biphenyl (SY1), phenanthrene (SY2), and pyrene (SY3), have been synthesized via a one-pot reaction with cheap commercially available starting materials for application in organic-inorganic hybrid perovskite solar cells (PSCs). The effects of the various pi-bridges on the photophysical, electrochemical, and electrical properties, and film morphologies of the materials, as well as on the photovoltaic properties of the PSCs, have been systematically investigated accordingly. Our results clearly show that HTM-SY3 with pyrene as the pi-bridge exhibits higher hole mobility and better hole extraction/transport and film formation abilities than the other two HTMs. Devices that employed SY3 as the HTM show impressive power conversion efficiency (PCE) values of 19.08% and 13.41% in (FAPbI(3))(0.85)(MAPbBr(3))(0.15)- and CsPbI2Br-based PSCs, respectively, which are higher than those of the reference HTM-SY1- and SY2-based ones. Our studies demonstrate a promising strategy to rationally design and synthesize low-cost and efficient HTMs through structural engineering for use in PSCs.

Various aromatic nitriles could be obtained in good yields by the treatment of aryl bromides with n-butyllithium and then pivalonitrile, followed by the treatment with molecular iodine at 70 degrees C, without metal cyanides under transition-metal-free conditions. The present reaction proceeds through the radical beta-elimination of imino-nitrogen-centered radicals formed from the reactions of imines and N-iodoimines under warming conditions.

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.

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.

In the course of studying silicon modifications to improve emission properties of commonly used organic compounds, biphenyl with dimethylsilylvinyl groups in the para position (3-Si) was investigated. A comparative study was performed on the exact C-analogue (3-C) and expanded to biphenyl and dimethylbiphenyl to emphasize the general trend observed. Compound 3-Si displayed emission properties clearly different than all of the investigated hydrocarbon compounds, i.e. twice stronger fluorescence (phi(f) = 0.6) and a 3-times larger radiative rate constant as compared to 3-C in acetonitrile. Searching for the source of the unique emission of 3-Si, singlet and triplet processes were investigated for all of the compounds using steady-state and time-resolved methods, and their principal photophysical parameters are reported. Experimental work was supported by the theoretical predictions obtained using the EOM-CCSD method. The results led to the conclusion that the strong emission of 3-Si must be due to silicon’s presence that enhanced intensity borrowing from the strongly allowed S0 -> S2 transition and the larger S1 -> S0 transition moment.

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.

The purpose of this work is to prepare effective adsorbents for simultaneously removing Hg(ii) ion and aromatic pollutants in water, which still remains a great challenge presently due to their different physicochemical properties. Herein, two new thiol-/thioether-functionalized porous organic polymers were prepared and characterized by scanning electron microscopy, infrared spectra, C-13 CP/MAS nuclear magnetic resonance spectra, energy-dispersive X-ray spectroscopy, elemental analysis, thermo-gravimetric analysis, and nitrogen adsorption-desorption isotherms. The results showed that the two adsorbents had a loosely porous structure, high BET surface area, and good thermal and chemical stability. The optimal pH value for the two new adsorbents to uptake Hg(ii) was 3-4. The new adsorbents presented a high adsorption ability with the maximum adsorption capacity of 180 mg g(-1) for Hg(ii) and 358-452 mg g(-1) for aromatic pollutants (toluene and m-xylene as models) and acceptable/fast binding kinetics for Hg(ii) and aromatic pollutants, respectively. The adsorbents also showed high adsorption selectivity for Hg(ii) in the presence of commonly coexisting metal ions. Moreover, the two adsorbents had good simultaneous removal ability for Hg(ii) and the aromatic pollutants at different concentrations and good reusability. Finally, the two new adsorbents were used successfully for the simultaneous and highly efficient removal of Hg(ii) ion and aromatic pollutants in simulated sewage with removal efficiencies higher than 88% for Hg(ii) and higher than 93% for the aromatic pollutants (10 mg of adsorbent mixed with 10 mL of sewage containing Hg(ii) and the aromatic pollutants at 10 g mL(-1) for each one), indicating their great potential to be applied for the simultaneous removal of Hg(ii) and aromatic pollutants in real sewage or wastewater.
