Donor–Acceptor Fluorophores for Energy-Transfer-Mediated Photocatalysis [PDF]

, 2018
Triplet–triplet energy transfer (EnT) is a fundamental activation pathway in photocatalysis. In this work, we report the mechanistic origins of the triplet excited state of carbazole-cyanobenzene donor–acceptor (D–A) fluorophores in EnT-based ...

Organic Afterglow Vesicles

Advanced Science, EarlyView.
This work constructs organic afterglow vesicles through polymerization‐induced self‐assembly (PISA), integrating thermally activated delayed fluorescence (TADF) type organic afterglow emitters into block copolymer nanostructures. The resulting vesicles exhibited significant room‐temperature afterglow, with an emission lifetime exceeding 200 ...

High‐Efficiency TADF Dendritic Emitters Enabled by Synchronously Inhibiting Degenerated Triplet Excited States and Structural Relaxation Toward Solution‐Processed OLEDs with EQE Over 33%

Advanced Science, EarlyView.
Asymmetrical thermally activated delated fluorescence dendritic emitters are delicately constructed through symmetry breaking strategy, and near‐unity photoluminescence efficiency and excellent reverse intersystem crossing process are achieved via breaking the degeneracy of vibrational levels and boosting the spin flip of triplet excitons.
