Published: March 18, 2023

Abstract The excited‐state tuning of luminescent metal–organic compounds has made great progress in the fields optical imaging, photocatalysis, photodynamic therapy, light‐emitting devices, sensors, and so on. Although with high luminescence efficiency can be realized via enhanced molecular rigidity heavy‐atom effect, their corresponding lifetimes are still limited on order a nanosecond to millisecond, owing inherent competition between luminous lifetime. Therefore, advanced applications (i.e., persistent afterglow information security, anti‐counterfeiting, smart materials, among others) related long (LPL, typically lifetime larger than millisecond) seriously hindered. This review gives timely systematic summary for realizing room‐temperature phosphorescence (RTP)‐type thermally activated delayed fluorescence (TADF)‐type LPL during last few years. Particularly, based perspectives time, space, energy dimensions, fundamental materials design coordination assembly systematically described first time. Moreover, internal external factors influencing properties terms efficiency, lifetime, color illustrated. Last but not least, challenges also discussed developing from compounds.
