Optical and electro-optical properties have been investigated on beta-carotenes and related linear conjygated polyenes and polymers, inciuding diphenyl (DP) -octatetoraene, DP-hexatoriene, DP-butagene, poly silanes and polydiacetylenes, in the form of crystals and thin films, by means of third-order nonlinear optical spectroscopy such as electro-modu lated absorption spectroscopy, third-order harmonic generation spectroscopy, two-photon absorption spectroscopy and others. As a result, details of quasi-one-dimentional exciton structures in these linear conjugated molecules have been nelucideted. An important outcome is the first finding of specific polydiacetylenes which exhibit a reversible photo-induced phase transition between the two different electronic phases.

本文利用三阶非线性光学光谱技术，如电调制吸收光谱、三阶谐波产生光谱、透射电子显微镜、透射电子显微镜等，研究了β-胡萝卜素及其线性共轭多烯和聚合物，包括二苯基辛四烯、二苯基己三烯、二苯基丁二烯、聚硅烷和聚二乙炔的晶体和薄膜的光学和电光性质。双光子吸收光谱学和其它。结果阐明了这些线性共轭分子中准一维激子结构的细节。一个重要的成果是首次发现了特定的聚二乙炔，它们在两个不同的电子相之间表现出可逆的光致相变。
