Unlocking Non-Kasha Room Temperature Phosphorescence in Azulene-based Cocrystal

Abstract

Herein, we unveil non-Kasha room-temperature phosphorescence and fluorescence in precisely tailored, azulene-embedded cocrystals. Comprehensive delayed emission experiments, supported by theoretical investigations, confirm the remarkable viability of singlet excitons and long-lived triplet excitons emanating from higher-energy states, bearing profound implications in next generation optoelectronics.
