Recent Advances of Pure Organic Room Temperature Phosphorescence Materials for Bioimaging Applications

Bioimaging, as a powerful and helpful tool, which allows people to investigate deeply within living organisms, has contributed a lot for both clinical theranostics and scientific research. Pure organic room temperature phosphorescence(RTP) materials with the unique features of ultralong luminescence lifetime and large Stokes shift, can efficiently avoid biological autofluorescence and scattered light through a time-resolved imaging modality, and thus are attracting increasing attention. This review classifies pure organic RTP materials into three categories, including small molecule RTP materials, polymer RTP materials and supramolecular RTP materials, and summarizes the recent advances of pure organic RTP materials for bioimaging applications.
