Metal-Organic Cages Based on Phosphorescent Organometallics

Abstract

During the last two decades, metal-organic cages (MOCs) have been extensively investigated and well documented. Meanwhile, phosphorescent MOCs have emerged as a kind of new MOC material but have not been given much attention. The diversity of their structures and their flexibility of self-assembly result in various luminescent behaviors. Additionally, their special photoactive properties are quite attractive in the background of photochemistry and worthy of discussion. Here, we would like to introduce the recent development of phosphorescent MOCs, including their structures, syntheses, photophysical properties and possible applications. This minireview may hopefully inspire the development of novel phosphorescent MOCs and also facilitate promising applications.
