The radiative decay rate constants are within the same order of magnitude, and thus the marked difference in the quantum efficiencies is ascribed to the different thermal deactivation pathways via the metal-centered ( 3MC) states and the nonradiative vibrational relaxation.

The calculated results show that the transition nature of an emissive T 1 state can be assigned to the mixture of metal-to-ligand charge-transfer ( 3MLCT) and intraligand charge-transfer ( 3ILCT) states.

In order to reveal the coordinating effect of these isomerized ptz ligands on the photophysical properties, density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations were performed to investigate the geometrical and electronic structures, absorption and emission properties, and radiative and nonradiative process of iridium complexes. On Monday, March 7, from 3:00 pm 5:00 pm the Arizona Historical Society, Marked By COVID and the Covid Memorial Quilt will join together to host a public memorial, COVID-19 Victims and Survivors Memorial Day at the Arizona Heritage Center in Tempe, Arizona. Four structurally similar blue phosphorescent iridium complexes with isomerized phenyltriazole (ptz) ligands, ( 1), ( 2), ( 3), and ( 4), exhibit marked differences in their quantum efficiencies.
