Advances in crystalline metal–organic photochromic materials

Abstract

Metal-organic materials have undergone rapid advancements due to their unique structural properties and exceptional application potential. As a key branch, crystalline metal-organic photochromic materials (CMOPMs), have attracted significant attention for their ability to modulate physical properties in response to light stimulation, thereby expanding the research landscape of metal-organic materials in areas such as molecular switch, gas adsorption and separation, and sensing applications. Furthermore, light as a renewable and clean energy source significantly enhances its application potential. In this feature article, we provide a brief summary of the design and synthesis strategies, classification, and applications of CMOPMs. Finally, we present the opportunities and challenges for the development of CMOPMs.
