摘　　要：为了探究不同给电子体与共轭桥和受体的匹配效应,以咔唑为共轭桥,以久洛尼定(GLN)为电子给体,2-[(3-氰基-4,5,5-三甲基呋喃-2(5H)-亚烷基)]丙二腈(TCF)作为电子受体,通过Wittig和Vils meier等反应合成了一种新型生色团。采用核磁共振氢谱(^(1)H NMR)对其结构进行了表征,并通过热重分析、紫外吸收光谱以及密度泛函数理论(DFT)计算对分子的稳定性以及微观非线性光学性能进行了研究。结果表明,新型生色团展现了良好的非线性光学性能以及热稳定性。In order to explore the matching effects of different electron donors with conjugate bridges and acceptors,a new carbazole-based nonlinear optical material was synthesized through Wittig and Vilsmeier reactions with carbazole as the conjugate bridges,with julonidine as the electron donor,and 2-[3-cyano-4,5,5-trimethylfuran-2(5H)-alkyl]-malononitrilel(TCF)as the electron acceptor.Its structure was characterized by ^(1)H nuclear magnetic resonance(^(1)H-NMR),and the stability of the molecule and low-light nonlinear optical properties were studied by thermogravimetry,ultraviolet absorption spectrum,and density functional theory(DFT)calculations.The results showed that the chromophore with carbazole as the conjugated structure exhibited good nonlinear optical properties and thermal stability.
