Effects of geometric isomerism and regioisomerism on photophysical properties of iridium( iii ) complexes

Year: 2026

Type: article

Abstract: substituent positional variations on the ligand framework, significantly influencing the absorption spectral profiles and optical bandgap. Analysis of spin-orbit coupling and key rate constants reveals that the studied complexes are predominantly phosphorescent emitters, with complex 6 showing a certain tendency towards thermally activated delayed fluorescence (TADF). This work may provide a theoretical reference for experimental synthesis, and the relevant luminescent materials are expected to find applications in OLEDs, thereby supporting their subsequent use in organic electroluminescence.
