摘要
借助于金属本身具有丰富的光、电、磁性质,将金属砌块引入到光致变色体系中,是获得结构新颖、性能独特金属分子开关的一条有效途径.本文简要介绍了光致变色分子开关的相关特征、种类、变色机理及其潜在应用;系统介绍了二芳基乙烯分子开关的研究概况;重点介绍了光致变色金属(Ru,Pt,Ln)-二芳基乙烯分子开关方面的研究成果及其在相关领域的潜在应用.最后对该领域的研究热点和发展趋势作了展望.
By virtue of a variety of optical, electrical, and magnetic properties of metallic ions, a feasible approach to achieve novel structural and unique performance molecular switches by introducing metallic ions into photochromic compounds has been developed. This review outlines briefly the relative properties, photochromic systems, photochromic mechanisms and potential applications of molecular switches, introduces systematically the research progresses of dithienylethene （DTE） and its derivatives, and highlights the research findings together with the applications in various fields of metallic dithienylethenes （M-DTE, M=Ru, Pt, Ln）. Finally, the research trends on such topics in near future are discussed.
