摘要
以咔唑和三苯胺基团作为电子给体,酮基作为电子受体,碳碳双键作为π桥,设计合成了一种具有D-A-π-D构型的化合物L,通过核磁共振氢谱、碳谱、质谱和红外光谱对化合物L进行了表征。利用紫外可见吸收光谱和荧光发射光谱,并结合含时密度泛函(TD-DFT/B3LYP)理论,研究了化合物L在不同极性溶剂中的光物理性质及聚集诱导发光(AIE)性质,结果表明化合物L对极性较为敏感,当含水量为80%时化合物L的荧光强度达到最大值,约是纯乙醇的17.5倍,是一种典型的AIE分子。
Compound L with D-A-π-D configuration was designed and synthesized using carbazole and triphenylamine units as electron donors,keto group as an electron acceptor and olefin bond asπbridge,which was characterized by 1 H NMR,13C NMR,ESI-MS and IR spectroscopy.The photophysical properties and aggregate-induced emission(AIE)proper⁃ties of compound L in different polar solvents were investigated by using UV-vis absorption and fluorescence emission spectra combined with time-dependent density functional(TD-DFT/B3LYP)theory.The results indicated that compound L was sensitive to polarity.When the water content is 80%,the fluorescence intensity of compound L reaches the maximum,about 17.5 times that of pure ethanol,which is a typical AIE molecule.
