Study of Spectroscopy on the characteristic narrow-band phosphorescence of Pt-complexes |
| 초록 |
In order to understand the relation between the narrowing of emission band and structural changes, we synthesised tetradentate Pt-complexes; Pt-1 has directly connected two carbazole (Cz) moieties, Pt-2 has additional two methyl groups to Pt-1, and Pt-3 is one Cz moiety. The absorption and emission spectra of Pt-1 are identical with those of Pt-2. The emission of Pt-3 observed at shorter wavelength compared to others. The 0-0 vibronic band of all Pt-complexes was quite intense compared to the 0-1 vibronic band, which may due to the restricted structure of tetradentate ligand. To determine the cause of this spacing, we have carried out the theoretical study using the DFT calculation and the analysis of IR-spectra. Also, we have carried out transient Raman experiment to get the vibronic informations of excited Pt-1. The HOMO orbital is populated Cz moiety, but the LUMO orbital is localized at the terminal pyridine moiety and the terminal moiety is less restricted and more flexible. |
