金属配合物的光敏性早已为人所知。早期对简单无机配体（如NH3， CN-）的金属配合物的光取代和光氧化还原分解反应进行了研究，随后对其光物理行为（发光量子产率和寿命）和金属配合物在双分子过程中的使用（能量和电子转移）进行了准确的研究。大量的配合物对光分解稳定，但能够经历激发态氧化还原过程，已被用于光能和化学能的相互转换。最近，超分子化学和光化学的结合导致了能够执行光诱导功能的多组分系统的设计和构建。在这一领域，发光和/或光氧化还原活性金属配合物目前被用作自下而上方法构建分子器件和机器的基本组成部分。举例说明了用于处理光信号的分子装置和基于配位化合物的以光能为动力的分子机器。(C) 2007 Elsevier B.V.版权所有
The photosensitivity of metal complexes has been known for a long time. Early studies on ligand photosubstitution and photoredox decomposition reactions of metal complexes of simple inorganic ligands (e.g. NH3, CN-) have been followed by accurate investigations on the photophysical behavior (luminescence quantum yields and lifetimes) and on the use of metal complexes in bimolecular processes (energy and electron transfer). A large number of complexes, stable towards photodecomposition, but capable of undergoing excited state redox processes, have been used for interconverting light and chemical energy. More recently, combination of supramolecular chemistry and photochemistry has led to the design and construction of multicomponent systems capable of performing light induced functions. In this field, luminescent and/or photoredox reactive metal complexes are presently used as essential components for a bottom-up approach to the construction of molecular devices and machines. Examples of molecular devices for processing light signals and of molecular machines powered by light energy, based on coordination compounds, are illustrated. (C) 2007 Elsevier B.V.
