25834-16-6, Name is 1,3-Isobenzofurandione, 4,7-dibromo, belongs to benzofurans compound, is a common compound. category: benzofuranIn an article, once mentioned the new application about 25834-16-6.

We report on two pushpull type polymer semiconductors involving phthalimide derivatives as electron withdrawing units. The solubility and energy level of phthalimide could be easily controlled by introducing various functional groups in its nitrogen site. Additionally, the VOC value of polymer semiconductor materials with phthalimide as an electron withdrawing unit could be efficiently enhanced because of the low HOMO energy level of phthalimide. Nevertheless, there are just a few of studies regarding the use of phthalimide in OPVs. In this study, we synthesized two photovoltaic polymer materials based on phthalimide with high VOC value, PFTPT and PCTPT. Between the two polymers, PCTPT/PC71BM-based photovoltaic cell afforded the best PCE value of 1.4% (VOC=0.94 V, JSC=4.41 mA/cm2, FF=0.33) under 100 mW/cm2 irradiation. In addition, a promising strategy for the development of high performance photovoltaic polymers with phthalimide derivatives as electron withdrawing units was investigated.

A new series of donor-acceptor-donor type trimeric monomers bearing substituted phthalimide units as acceptor units and thiophene and 3,4-ethylenedioxythiophene (EDOT) as donor units was synthesized and characterized. The strength of acceptor units and intramolecular charge transfer between donor and acceptor units were investigated by using electrochemical and optical methods. The main advantage of phthalimide unit over other acceptor units is the ease of its functionalizability. Thus, utilizing this property, a phthalimide derivative (E2P-POSS) bearing polyhedral oligomeric silsesquioxane (POSS) cage was introduced successfully with EDOT and polymerized electrochemically. The corresponding electroactive polymer, PE2P-POSS, has a band gap of 1.72 eV and is an electrochromic polymer: gray when neutralized and eggplant purple when oxidized.

A novel polyaniline derivative containing an emissive chromophore in its backbone was prepared by a palladium-catalyzed aryl amination. The incorporation of a 3,6-diamino phthalimide dye imparts a red color to the leucoemeraldine base analogues while reducing the overall electron density in the chain. The incorporated dye acts as a colorimetric tag indicative of the oxidation state of the polyaniline analogue. The three different oxidation states of the polymers were unambiguously characterized by comparison with an oligomeric model compound using IR and UV-vis spectroscopy. The emeraldine analogue of the polymer shows a measured conductivity of 10-5 S cm-1 and unlike polyaniline, this material exhibits yellow fluorescence in solution. A cyclic tetramer was also isolated from the reaction mixture and 2D-WAXS measurements on an extruded fiber reveal that it forms a hexagonal columnar packing.

A novel small molecule-based organic donor SM [(2Z,2?Z)-3,3?- (((1E,1?E)-(2-cyclohexyl-1,3-dioxoisoindoline-4,7-diyl)bis(ethene-2, 1-diyl))bis(4,1-phenylene))bis(2-(4-nitrophenyl)-acrylonitrile)] featuring 2-(4-nitrophenyl)acrylonitrile as the acceptor and a pi-conjugation bridge composed of phthalimide and styryl units, with an A-pi-A type structure, has been synthesized. It showed a long wavelength absorption band having an absorption maximum around 635 nm and the optical bandgap was 1.63 eV, which is lower than most reported conjugated polymers, including poly(3-hexylthiophene) (P3HT). The photovoltaic properties were investigated by constructing bulk heterojunction organic solar cell devices using SM as the electron donor and fullerene derivatives, i.e. PC60BM and PC70BM as the electron acceptors with the device architecture ITO/PEDOT:PSS/SM:PC 60BM or PC70BM/Al. The effect of the SM/fullerene derivative weight ratio and the processing solvent were carefully investigated to improve the performance of the organic solar cells. The optimized organic solar cell with SM:PC60BM and SM:PC70BM cast from THF solvent, at a weight ratio of 1:3 showed power conversion efficiencies (PCEs) of about 1.70% and 2.56%, respectively. The enhanced value of PCE for the BHJ photovoltaic device based on PC70BM is related to the better absorption of PC70BM in the visible region compared to that of PC60BM. The SM:PC70BM blends cast from a DIO-THF mixture and subsequent thermal annealing exhibited improved PCEs of 3.68% and 4.14%, respectively.

Two donor-acceptor (D-A) alternating copolymers (P1 and P2) with phthalimide or thieno[3,4-c]pyrrole-4,6-dione as the electron acceptor and bithiophene as the electron donor have been synthesized by Stille polycondensation. Both polymers showed good thermal stability and a low HOMO level. Organic field-effect transistor (OFET) devices with common architectures were fabricated to evaluate and compare the FET properties of the two polymers. Though P2 exhibits better coplanarity than P1, the FET results revealed that both the hole mobility and current on-off ratio of P1 are more than one order of magnitude higher than P2. Theoretical calculations and AFM were conducted to analyze the reason for this very interesting result, and it was found that polymer chain conformation is another important factor (in addition to coplanarity) for polymers to obtain high FET performance.

Coumarin and Moracin Derivatives from Mulberry Leaves (Morus albaL.) with Soluble Epoxide Hydrolase Inhibitory Activity

This study identified three coumarins (1-3), and six moracin derivatives (4-9). The structures of these natural compounds were determined by the spectroscopic methods, including 1D and 2D NMR methods, and comparison with previous reported data. All of the isolated compounds were assessed for the effects on the soluble epoxide hydrolase (sEH) inhibitory activity. Among them, compounds1-7exhibited significant inhibitory effect with 100% inhibitory, with IC(50)values of 6.9, 0.2, 15.9, 1.1, 1.2, 9.9, and 7.7 mu M, respectively. A kinetic study revealed that compounds1-4, and6were competitive types of inhibitors, compounds5and7were mixed types of inhibitors.

Benzo[b]tellurophenes as a Potential Histone H3 Lysine 9 Demethylase (KDM4) Inhibitor

Gene expression and tumor growth can be regulated by methylation levels of lysine residues on histones, which are controlled by histone lysine demethylases (KDMs). Series of benzo[b]tellurophene and benzo[b]selenophene compounds were designed and synthesized and they were evaluated for histone H3 lysine 9 demethylase (KDM4) inhibitory activity. Among the carbamates, alcohol and aromatic derivatives, tert-butyl benzo[b]tellurophen-2-ylmethylcarbamate (compound 1c) revealed KDM4 specific inhibitory activity in cervical cancer HeLa cells, whereas the corresponding selenium or oxygen substitute compounds did not display any inhibitory activity toward KDM4. Compound 1c also induced cell death in cervical and colon cancer but not in normal cells. Thus, compound 1c, a novel inhibitor of KDM4, constitutes a potential therapeutic and research tool against cancer.
