  The synthesis and photoluminescence characteristics of novel 4-aryl substituted thiophene derivatives with bis-diarylacrylonitrile unit

  摘要：

  (Z)-2-(4-Bromophenyl)-3-(4-(5-((Z)-2-cyano-2-phenylvinyl)thiophen-3-yl)-phenyl)acrylonitrile was synthesized by (2)-3-(4-(4-formylphenyl)-thiophen-2-yl)-2-phenylacrylonitrile and 2-(4-bromophenyl) acetonitrile through a base catalyzed condensation reaction, and then reacted with various aryl boronic acids under the catalyzing of Pd(PPh3)(4) to afford a series of novel 4-aryl substituted thiophene derivatives with bis-diarylacrylonitrile unit. The structures of the products were characterized using FTIR, H-1 NMR, C-13 NMR, and HRMS. The UV-vis absorption and photoluminescent spectra of these derivatives were investigated. These compounds emit 450-510 nm green fluorescence in the solid state and 446-491 nm emission in CH2Cl2 solution under UV irradiation. Analysis revealed good thermal stability with a decomposition temperature ranging from 301 to 378 degrees C. (C) 2012 Elsevier Ltd. All rights reserved.
