The synthesis and photophysical study of efficient phosphorescent iridium(III) complex having two different (CN) ligands are reported. In order to improve the luminescence efficiency by avoiding triplet-triplet (T-T) annihilation and study luminescent mechanism of the heteroleptic iridium complex, Ir(piq-3F)2 (dpq-4F) is designed and prepared where piq-3F and dpq-4F represent 1-(4′-fluorophenyl)isoquinoline and 2-(3′-fluorophenyl)-4- phenylquinoline, respectively. We thought that both piq-3F and dpq-4F ligands can act as a source of energy supply because of the relative HOMO energy level and the luminescence lifetime of homoleptic Ir complexes Ir(piq-3F)3 Ir(dpq-4F)3. However the UV-vis absorption spectra and the PL spectra of Ir(piq-3F)2 (dpq-4F) is more similar to that of Ir(piq-3F)3. In spite of lower triplet energy level of dpq-4F, the excitation energy is not intramolecular transferred from two piq-3F ligands to one dpq-4F ligand. The luminescence occurs mainly at piq-3F ligand. It is due to the strong MLCT characteristic of piq-3F ligand. To analyze luminescent mechanism, we calculated these complexes theoretically by using computational method.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 19493-44-8
