光响应分子由于其光照射能力而被广泛研究，所述光照射能力使得能够在新兴的分子电子和光子器件中调制某些物理和化学性质。对于先进的光子应用，具有光致变色单元作为光响应配体的光致变色金属络合物是高度期望的，因为它们允许改善光致变色性质和它们的光开关功能。综述了近年来含光致变色单元的发光金属配合物的研究进展。光致变色金属配合物的发光开关特性取决于特征电子跃迁。光致变色金属配合物的电子跃迁可分为三类：（1）配体的π-π * 跃迁，（2）过渡金属配合物中的金属-配体电荷转移（MLCT），（3）镧系配合物中的f-f跃迁。近年来，使用具有光致变色单元的各种金属配合物的发光调制已经被广泛研究，并且在先进光子学领域中预期用于未来分子开关器件的各种应用。本文在文献综述和研究工作的基础上，综述了近年来含光致变色单元的发光金属配合物的研究进展。(C)2010 Elsevier B.

Photo-responsive molecules have been studied extensively because of their light irradiation abilities that enable modulation of certain physical and chemical properties in emerging molecular electronic and photonic devices. For advanced photonic applications, photochromic metal complexes that have photochromic units as the photo-responsive ligand are highly desirable, as they allow improvement of the photochromic properties and their photo-switching functionality. This article focuses on recent progress in luminescent metal complexes with photochromic units. Luminescence-switching properties of photochromic metal complexes depend on characteristic electronic transitions. The electronic transitions of photochromic metal complexes can be divided into three categories: (1) pi-pi* transition of the ligand, (2) metal to ligand charge transfer (MLCT) in transition-metal complex, and (3) f-f transition in lanthanide complex. Luminescence modulation using various metal complexes with photochromic units has been studied extensively in recent years, and various applications for future molecular switching devices are expected in the field of advanced photonics. Based on the literature and our studies on luminescent metal complexes with photochromic units, we report on the recent progress of luminescent metal complexes with photochromic units.
