中文摘要： 本项目制备合成一类新型的带有光致异构化侧基的酞（萘）菁类大环平面化合物分子,作为新的平面自组装基元，并实现新的功能化性质。二芳烯类光致异构化侧基的引入，使酞（萘）菁类分子在不同条件下，进行光控可逆的超分子自组装，也即实现超分子的光致变色。在此基础上提出此类光控自组装的检测和表征方法，发展大环平面分子共面化光可控自组装技术和理论。并通过研究其热控自组装、手性自组装以及薄膜、表面、凝胶和晶体中的自组装，完备多维可控自组装技术和机理，尝试平面超分子可控自组装的三阶非线性全光开关等有机光电功能应用。

英文摘要： This research is to develope a new type of big ring compounds with side groups of light-induced isomerization as planar self-assemble units, for instance, macrocyclic phthalocyanine(phthalocyanine)-diarylethene (photochromic phthalocyanine) system. In different conditions, the status of supramolecular self-assembly can change reversibly, that means to realize the photochromism of supramolecules. We proposed the detection and characterization of such self-assembly system, and develop the controllable self-assembly techniques and theory of aggregation based on the effect of planar surface role. We also devote ourselves to the study of thermal-control self-assembly, chiral self-assembly, and self-assembly in films, surface, gels and crystals. We want to apply the plane controllable self-assembled system to the third-order non-linear full-wavelength switches or other organic optoelectronic devices by means of comprehensive utilization of light and heat controled self-assembly process.
