Mo, Daize; Chen, Hui; Zhou, Jiadong; Han, Liang; Zhu, Yulin; Chao, Pengjie; Zheng, Nan; Xie, Zengqi; He, Feng published the artcile< Isomeric effects of chlorinated end groups on efficient solar conversion>, Recommanded Product: 5-Chloroisobenzofuran-1,3-dione, the main research area is isomeric chlorinated solar polythiophene electronic optoelectronic photovoltaic.

Isomers with subtle differences in their mol. structure often exhibit different electronic/optoelectronic properties, charge-transport behaviors and photovoltaic performances. In this work, we describe BTIC-2Cl-γ, BTIC-2Cl-δ, and BTIC-2Cl-β, three isomers with acceptor-donor-acceptor-donor-acceptor (A-D-A-D-A) structures, in which a fused benzothiadiazole is the donor (D) unit and a single chlorine atom substituted at the δ, β or γ position of the benzene-fused end groups is the acceptor (A) unit. In general, changes in the position of the chlorine atom were found to lead to significantly different absorptions, energy levels, and photovoltaic performances. Compared to BTIC-2Cl-δ, the BTIC-2Cl-γ isomer shows similar UV/Vis absorption, energy levels, and mol. packing, but slightly better photovoltaic performance. A crystallog. anal. of BTIC-2Cl-δ indicates that the mols. easily form a three-dimensional (3D) network due to the noncovalent interactions of Cl···S, Cl···π and Cl···N. When blended with PBDB-TF as an electron-donor material, the devices based on BTIC-2Cl-γ exhibited higher power conversion efficiency (PCE) of up to 15.04% with an increased voltage (Voc) of 0.90 V, which was better than that of BTIC-2Cl-δ-based devices (14.13%) and much higher than that of BTIC-2Cl-β-based devices (7.39%). Our studies demonstrate that having the chlorine atom at the different positions of the end groups clearly affects the photovoltaic properties of the resulting acceptors.

Functionalization with belt lanthanide groups allows for the crystallization and structural characterization of homometallic selenotantalates, CsK[Ln(H2O)6Se4(TaO2)6(OH)3O18]·nH2O (Ln = Eu/Gd, n = 14 (STD-Eu, STD-Gd) and Ln = Lu, n = 12 (STD-Lu)). The basket-shaped {Se4(TaO2)6} archetype is assembled in a simple one-pot reaction of Na2SeO3 and K8[Ta6O19]·17H2O in acidic aqueous medium (pH 2) and in the presence of hydrogen peroxide. This unit was proven to be an effective precursor for the preparation of a range of new POMs containing the {Se4(TaO2)6} unit. The lanthanide derivatives STD-Eu, STD-Gd and STD-Lu were fully characterized with single-crystal X-ray diffraction, IR spectroscopy, TGA and PXRD in the solid state. The photoluminescence and lifetime decay behaviors of STD-Eu were studied at room temperature, and the photoluminescence spectrum displays the characteristic emission of the Eu3+ cation. In addition, the catalytic activities of STD-Eu, STD-Gd and STD-Lu on the reaction of phthalic anhydride with phenylamines were studied. STD-Eu shows good catalytic activities for imidation reactions.

The saturated vapor pressures of 4-fluorophthalic anhydride and 4-chlorophthalic anhydride at various temperatures ranging from T = (426 to 560) K, and the isobaric vapor-liquid phase equilibrium data for binary system of 4-fluorophthalic anhydride (1) + 4-chlorophthalic anhydride (2) at pressures of 21.33 kPa, 41.33 kPa, 61.33 kPa and 81.33 kPa were measured exptl. by means of an inclined ebulliometer. The relationship between saturated vapor pressure and temperature was fitted by using two Antoine equations and the Antoine constants were acquired for 4-fluorophthalic anhydride and 4-chlorophthalic anhydride, resp. The semi-empirical method, Herington method was employed to test thermodn. consistency of the vapor-liquid equilibrium data. The isobaric vapor-liquid phase equilibrium data were fitted with three thermodn. models, which corresponded to Wilson, NRTL and UNIQUAC. The parameters of the three activity coefficient models were obtained by the method of nonlinear least-square regression. The calculated vapor-liquid phase equilibrium data with the three activity coefficient models agree very well with the exptl. values.
