摘　　要：根据成键特点,对基于有机光致变色的有机-无机杂化材料的光致变色特性及其作为多功能材料的研究进展进行分类介绍。配位共价键结合的配合物型杂化光致变色材料通过光致变色配体与金属离子间的螯合作用,不仅能提高光致变色单元的稳定性、抗疲劳性,同时可在整个大分子体系中实现电化学特性、能量转移、荧光发射的光致变色调控;键合较弱的插层、介孔型杂化光致变色材料利用宿主的耐久性可提高有机光致变色分子的稳定性、抗疲劳性,同时实现宿主磁性的光致变色可逆调控;离子键结合的新型有机–无机杂化光致变色材料具有以光电子转移为特征的热可逆固态光致变色行为。According to the chemical bond feature of hybrid materials,the photochromic properties of organic–inorganic hybrid photochromic materials was introduced which was based on the organic photochromic materials,as well as their investigative history as multi-functional materials.Through coordinate-covalent bond interaction between organic photochromic ligand and metal ions,complex photochromic compounds can not only improve the stability and fatigue resistance of photochromic unit,but regulate other features in the whole molecular system such as electrochemical property,energy transfer and fluorescence emission.With weak interaction between organic and inorganic unit,intercalate or mesoporous photochromic hybrid materials can provide host space to improve the stability and fatigue resistance of photochromic unit and reversibly regulate the host magnetic character reversibly simultaneously.A new type of organic–inorganic hybrid photochromic material,bond with ionic bond,owns reversible photochromic ability in solid state through photoelectron transfer.
