Photochromic compounds are well-known for their promising applications in many areas. In this context, many different photochromic families have been developed. As the early study of these photochromic compounds was mainly focused on the organic system, their photochromic reactivity was mainly derived from the singlet excited state. We hypothesized that the incorporation of the photochromic ligand to the transition metal complex and coordination complex systems would not only render the triplet state of the organic photochromic system more readily accessible due to the large spin–orbit coupling of the heavy metal center but also would lead to ready extension of the excitation wavelength to less destructive longer wavelength low-energy excitation. On the other hand, the long-lived triplet excited states of the metal complexes are also suitable for energy or electron transfer processes, which should lead to new photochromic behavior and photoswitchable functional properties.

与光致变色配体的配位化合物：易于调试和可见光致敏的光致变色

光致变色化合物以其在许多领域中的有前途的应用而闻名。在这种情况下，已经开发出许多不同的光致变色族。由于这些光致变色化合物的早期研究主要集中在有机体系上，因此它们的光致变色反应性主要来源于单重激发态。我们假设，将光致变色配体掺入过渡金属配合物和配位配合物系统中，不仅会由于重金属中心的自旋轨道耦合大而使有机光致变色系统的三重态更容易获得。准备将激发波长扩展到破坏性较小的长波长低能激发。另一方面，
