Recent progress with the application of organic room-temperature phosphorescent materials

Organic materials with room-temperature phosphorescence (RTP) emission have attracted extensive attention owing to their extraordinary properties, including long lifetime, large Stokes shift, and stimuli-responsiveness, and show bright prospects in broad fields. Numerous design strategies, such as creating a rigid environment through crystallization and supramolecular assembly, can be employed to improve the luminescent characteristics of RTP materials by restricting nonradiative transition, enhancing intersystem crossing, and so forth. This review summarizes recent progress with organic room-temperature phosphorescent materials from the perspective of practical applications, including luminescence and display, environmental detection, and bioimaging, and the challenges and prospects will be discussed at the end, which should assist with future research on the application of RTP materials.
