金属有机共轭配合物因其良好的氧化还原特性和丰富的光、电、磁等物理化学性质成为一种重要的响应性功能分子材料,是分子导线、分子开关、分子机器、分子存储、光电检测等应用的材料基础.本文主要介绍近几年本课题组在环金属配合物的分子设计及其氧化还原响应方面的工作进展,具体包括环金属双钌共轭配合物、环金属参与的不对称双中心共轭分子以及氧化还原多中心共轭配合物3种体系.这些化合物在较低电位处具有两步以上可逆氧化还原过程,并且每一种氧化还原状态具有明显不同的物理化学性质.以电化学电压为刺激响应手段,这些金属有机分子材料的近红外吸收和顺磁信号可以发生可逆变化,成为近红外电致变色及光信息存储的重要分子基础.
Due to their good redox properties and abundant physicochemical properties such as light, electricity and magnetism, metal-organic conjugated complexes have become an important responsive functional molecular material. They are molecular wires, molecular switches, molecular machines, molecular storage, Detection and other applications of the material basis.In this paper, the research group in recent years in the ring metal complexes molecular design and its redox response to the progress of work, including the ring metal double ruthenium conjugate complexes, Symmetric bi-center conjugate molecules and redox polycentroconjugate complexs.These compounds have two or more reversible redox processes at lower potentials and have distinctly different physicochemical properties for each redox state. Electrochemical voltage as a stimulus response means that the near-infrared absorption and paramagnetic signals of these metal-organic molecular materials can undergo reversible changes and become an important molecular basis for near-infrared electrochromism and optical information storage.
