Spectroscopic study on the satellite vibronic band in phosphorescent Pt-complexes with high colour purity |
| 초록 |
To understand the relationship between the narrowing of an emission band and structural changes, we synthesised tetradentate Pt-complexes. The absorption and emission spectrum of Pt-2 were identical to those of Pt-1. Pt-3’s emission was observed at a shorter wavelength compared to the others. We achieved phosphorescence with high colour purity by introducing a tetradentate ligand. All the Pt-complexes showed a vibronic structure in the emission spectra measured at 77 and 300 K. The 0-0 vibronic band of the Pt-complexes is quite intense compared to the 0-1 vibronic band, which may be due to less structural change of the fused tetradentate ligand in the excited state relative to the ground state. To understand the origin of the satellite vibronic bands, we carried out vibrational spectroscopic (IR and Raman) measurements and theoretical calculations to analyse the infrared spectrum. |
