新型含吲哚基团的光电功能材料

New Indole-Based Opto-Electronic Materials

本文较为系统地阐述了吲哚在光电功能材料各个领域的发展概况,主要包括光致变色、电致发光和非线性光学材料。较为全面地总结了吲哚(苯并五元氮杂环)的结构特点和独特的富电子性对光致变色材料和电致发光材料的紫外可见吸收波长、荧光发射波长、发光强度、量子效率等的影响,以及对制约非线性光学材料发展的重要难题之一——非线性和透明性矛盾的克服。

The recent progress of indole-containing opto-electronic materials is reviewed, including photochromism, electroluminescence and non-linear optical materials. The affect of the structural characteristcs and the rich electron cloud of indole, which is named as benzopyrrole, on the UV-vis absorption, emission wavelength, fluorescence intensity, quantum yield of the photochromism and electroluminescent materials is summarized. As to the non-linear optical materials containing indole-based chromophores, they all show a combination of large nonlinearity and relatively good transparency among the chromophores, providing a new method for defeating the ＂nonlinear-transparency tradeoff＂, which is one of the main problems that restrict the development of the non-linear optical materials.
