| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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 as π bridge, 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. |
