Substituent and Hydrostatic Pressure Regulation of Triplet Exciton Dynamics in Organic Room-Temperature Phosphorescent Crystals.
Organic room temperature phosphorescence (RTP) materials rely on efficient utilization of triplet excitons, yet the microscopic relationship among molecular distortion, crystal packing, and triplet decay dynamics remains insufficiently understood. Herein, we employ multiscale excited-state calculations combined with cr...
