Recent Advances of Pure Organic Room Temperature Phosphorescence Based on Functional Polymers

ConspectusThe phosphorescence is produced by the radiative transition of the excited triplet state which is generated by the intersystem crossing (ISC) from the excited singlet state. Compared with fluorescence, it has a longer luminescence lifetime and larger Stokes shift, so phosphorescent materials have great application value in fields such as displays, anticounterfeiting, and imaging. But due to the low ISC rate of organic molecules, the slow radiative transition rate of the triplet state, and the large nonradiative energy loss caused by molecular vibration, pure organic room temperature phosphorescence (RTP) is usually difficult to obtain. Among the most widely used strategies including crystal assembly,…
