| 摘 要： | 本文设计合成了一系列以三氮唑为电子受体的双生色团化合物。光谱研究表明这些分子的发光性质不仅取决于电子转移驱动力,也取决于间隔基和电子给体的尺寸。有些分子的发光在pH1～3范围内发生急剧变化,荧光量子产率相对于pH值的变化是一个双稳体系而具有光控分子开关性质。

| Abstract: | A series of bichromophore compounds containing triazole group as an electron acceptor were designed and synthesized. The results of photospectroscopic study reveal that the emission properties of these compounds are depended on not only the electron transfer driving force, but also the linking group and the size of the electron donor group. The fluorescence emission of some of the molecules dramaticly change in the region of pH 1～3. The plot of the fluorescence quantum yield vs. pH displays a bistable system, which implies that these molecules possess photo switching property. |
