中文摘要： 光致变色材料在信息显示、光信息存储、非线性光学、光开关等领域受到广泛关注。新型无机-有机杂化光致变色材料不仅可以结合无机和有机光致变色材料各自的优点，而且无机和有机组份之间的协同作用，可以使杂化材料呈现出新颖的功能。本项目拟从新型无机-有机杂化光致变色材料的关键结构因素和变色能级特点的研究出发，通过结构设计和能带调控，降低杂化光致变色材料消色所需要的势垒，以解决这类材料存在的消色速度慢的共性科学问题。在此基础上，以共价键、配位键、氢键的方向性以及有机组份的结构导向性为结构设计的出发点，通过对构筑基元之间相互作用的调节，改变材料的能级、能带及载流子特性，调节光激发过程，研究杂化材料中载流子输运、电子和能量的转移及传递等物理化学基本过程，结合理论计算，探讨光致变色的结构因素和无机和有机组分的协同机制，揭示其内在规律，为结构设计高性能的无机－有机杂化光致变色材料提供新思路。发表12-15篇论文。

英文摘要： Photochromic materials have been widely concerned in information display, optical data storage, nonlinear optics, optical switch, and other fields. New type of inorganic-organic hybrid photochromic materials not only can combine the advantages of inorganic and organic photochromic materials respectively, and the synergy between inorganic and organic components, can make the function of hybrid materials present a novel. This project is from the new type of inorganic and organic hybrid key structural factors of photochromic materials and color level characteristics of research, through structure design and take control, reduce the hybrid photochromic materials required for decolorization of barrier, in order to solve this kind of material to slow the decolorization of common scientific problems. On this basis, by covalent bonds, coordination bond, the direction of the hydrogen bond and the structure of organic components could serve as the starting point of structure design, through to the construction of the interaction between primitive adjustment, change the energy of a material, energy band and carrier features, adjust the optical excitation process, study carrier transport in hybrid materials, electronics and energy transfer and transfer of basic physical and chemical process, in combination with theoretical calculation, the structure factors of photochromic and coordinated mechanism of inorganic and organic components, reveals its inherent law, for the structure design of high performance inorganic - organic hybrid photochromic materials provide new train of thought. Published 12 to 15 papers.
