Xia et al propose a strategy to construct RTP materials by in situ encapsulation of phosphors into HOFs Compared with free phosphors the obtained HOFsphosphors RTP materials show highperformance RTP in air and water Meanwhile triplettosinglet Förster resonance energy transfer and luminescent films are obtained via the HOFbased RTP strategy
Furthermore by applying high hydrostatic pressure for the BpOEt crystal the RTP emission efficiencies and lifetimes are enhanced and blueshifted All of these results demonstrate the crucial role of molecular structure and stacking modes as well as the hydrostatic pressure effect in regulating RTP properties
ConspectusIn recent years purely organic roomtemperature phosphorescence RTP has aroused wide concern and promotes the development of the supramolecular phosphorescence Different from organic crystallization polymerization or matrix rigidification supramolecular strategy mainly takes advantage of the synergy between supramolecular coassembly and strong binding by macrocyclic host
Longlived and highly efficient room temperature phosphorescence RTP materials are in high demand for practical applications in lighting and display security signboards and anticounterfeiting Achieving RTP in aqueous solutions nearinfrared NIR phosphorescence emission and NIRexcited RTP are crucial for applications in bioimaging

Colorful RTP from blue to red with τ afterglow up to 1736 ms in carboxymethyl chitosan CC systems was achieved in this work To improve the RTP performance quaternary chitosan QC was introduced to build a binary matrix system which extended the lifetime by 200 ms and increased the phosphorescence quantum yield to 351 times
The RTP polymers possess inherent benefits such as excellent flexibility high thermal stability easy processing and low cost in largescale production and applications Besides complex polymer networks and multilevel microphase structures may provide a rigid environment for the generation of RTP along with dynamic photophysical properties
