Time‐Dependent Afterglow Color in a Single‐Component Organic Molecular Crystal
Angewandte Chemie International Edition, 2020AbstractAn organic crystal of 4,4′‐bis(N‐carbazolyl)‐1,1′‐biphenyl (pCBP) exhibits time‐dependent afterglow color from blue to orange over 1 s. Both experimental and computational data confirm that the color evolution results from well‐separated, long‐persistent thermally activated delayed fluorescence (TADF) and room‐temperature phosphorescence (RTP ...

A singlet oxygen-storing covalent organic framework for “Afterglow” photodynamic therapy
Journal of Colloid and Interface SciencePhotodynamic therapy (PDT) is an emerging treatment but often restricted by the availability of oxygen. Enhancing the lifespan of singlet oxygen (1O2) by fractionated generation is an effective approach to improve the efficacy of PDT. Herein, an imine-based nanoscale COF (TpDa-COF) has been synthesized and functionalized with a pyridone-derived ...
