Two isomers (TPA-CNa and TPA-CNb) consisting of twisted triphenylamine and cyanostilbene were synthetized by Knoevenagel condensation and C-N coupling reaction. The fluorescent colours of two isomers in crystalline state were sky-blue for TPA-CNa and gree

2-(4-Bromophenyl)-3-(4-diphenylaminophenyl)acrylonitrile was prepared by the base catalysed condensation of 4-diphenylaminobenzaldehyde and 2-(4-bromophenyl)acetonitrile. A series of α,β-diarylacrylonitrile derivatives containing both a biphenyl group and a triphenylamine unit were synthesized from 2-(4-bromophenyl)-3-(4-diphenylaminophenyl)acrylonitrile and boronic acids via a Suzuki reaction. The structures of these compounds were characterized using FTIR, 1H NMR, 13C NMR, MS and elemental analysis. The UV-vis absorption and photoluminescent spectra of these derivatives were investigated. These compounds emit green fluorescence with maximum emission peaks of 500-550 nm in CH2Cl2 solution and in the solid state under UV irradiation. Analysis revealed good thermal stability with a decomposition temperature ranging from 279-386 °C.
