摘　　要：以对溴苄基溴为原料,经Wittig-Horner-Emmons和Suzuki偶联反应合成了三苯乙烯-菲咯啉衍生物(DPP),其结构经^(1)H NMR、^(13)C NMR和MS表征。采用FL和UV-Vis研究了DPP在不同极性溶剂和聚集态中的光物理性能。结果表明:DPP具有溶剂质子化和聚集荧光增强性能;DPP在DMF溶液中的发射峰位于439.00 nm(1×10^(-5)M);相对于溶液状态,固体状态DPP发射峰仅红移了9.00 nm,呈现蓝色强荧光,其荧光强度是溶液状态的100.00倍。A triphenylethylene-phenanthroline derivative(DPP) was synthesized from 4-bromobenzyl bromide through Wittig-Horner-Emmons and Suzuki reactions. The structure of DPP was characterized by ^(1)H NMR,^(13)C NMR and MS. Photophysical properties of DPP in different polar solvents and aggregated states were studied by UV-Vis and FL. Results showed that DPP displays the protonation and aggregation-induced enhanced emission properties. The emission peak of DPP in DMF is at 439.00 nm. In the solid state, the emission peak exhibited 9.00 nm of red shift with strong blue fluorescence, which is 100.00 times higher than that in solution state.
