| 摘 要： | 咔唑衍生物及含咔唑基团的聚合物由于在光信息传导、全息照相和光折变等高科技领域的潜在应用前景而越来越受到重视［１～３］，大量有机光折变材料已被合成．其中一些含有咔唑成分的光折变材料具有很优异的性能．１９９４年，一种具有低玻璃化温度的ＰＶＫ掺杂体系的净增益参数达到２２０ｃｍ－１，而衍射效率也近似达到１００％．这一结果超过了已知的绝大多数无机物［２］．大多数咔唑衍生物及含咔唑基团的聚合物都具有良好的光电导性质，并且主要以空穴传导为主．但它们的迁移率和机理由于引入不同的侧基和掺杂物出现很大差别［４～６］…

| Abstract: | Anew difunctional photorefractive model molecule, 3-azo-4′-nitro-9-ethyl-carbazole was synthesized and its structure was characterized by 1HNMR and UVspectra. The results from Time-of-Flight experiment show that the sample exhibited good photoconductivity not only by hole transport but also by electron transport, which may be due to the reason that the molecule formed not only a delocalized system but also charge-transport complex, and contributed to its charge carrier mobility. |
