Chalcogen-Driven Conformational Control for Room-Temperature Phosphorescence and Zn2+ Coordination-Induced Delayed Fluorescence in Phenazine Derivatives.
Purely organic luminescent materials are pivotal for optoelectronics, with chalcogen-fused phenazines serving as basic building blocks owing to their strong electron donating ability and enhanced spin-orbit coupling effect. However, a systematic understanding of how the chalcogen identity governs intrinsic conformation...
