Dynamic Organic Phosphorescence Glass by Rigid‐Soft Coupling

Organic phosphorescence glass has garnered considerable attention owing to the excellent shaping ability and photophysical behavior, but facile construction from single‐component phosphors is still challenging. Herein, a rigid‐soft coupling design is adopted in organic phosphors of ICO, CCO and PCO, thus preparing phosphorescence glasses through melting‐quenching method to give excellent shaping ability and dynamic phosphorescence. RTP performance is significantly enhanced in the dense‐structure glass, and intriguing high‐temperature phosphorescence (HTP) is still observable even at 400 K. Direct patterning under UV irradiation is also achieved using photolithography technique, allowing for the creation of high‐quality afterglow patterns that can be reversibly erased and rewritten. This rigid‐soft conformation in organic phosphors elucidates a promising concept for achieving efficient RTP glass with wide application prospects.
