Synthesis, Crystal Structure and Luminescent Properties of 2-(4-Aminophenyl)-3-(4-(diphenylamino)phenyl)acrylonitrile

摘要

A novel triphenylamine derivative, 2-(4-aminophenyl)-3-(4-(diphenylamino)phenyl) acrylonitrile (L), was synthesized and characterized by NMR spectra and X-ray diffraction analysis. Compound L crystallizes in monoclinic, space group P21/n with a = 17.120(12), b = 6.753(5), c = 20.380(15), β = 113.043(8)°, Mr = 387.47, V = 2168(3)3 , Z = 4, Dc = 1.187 g/cm3 , μ = 0.071 mm-1 , F(000) = 816, R = 0.0475 and wR = 0.1410 for 16102 observed reflections (Ⅰ > 2σ(Ⅰ)). In the crystal structure, compound L was found to form antiparallel dimer stacks due to its specific intermolecular interactions, including C-H···N and N-H···π interactions. Fluorescence and thermal studies indicate that compound L has good optical properties and thermal stability.
