Highly resolved emission and excitation spectra of several specific sites are obtained by site-selective spectroscopy. For the preferentially investigated site (I → 0 at 16268 cm-1), the three substates I, II, and III of the T1 triplet state are separated by ΔEII-I = 2.9 cm-1 and Δ...
The lowest triplet state T 1 of Ir(btp) 2(acac) doped into CH 2Cl 2 is studied by site-selective and time-resolving emission and by excitation spectroscopy... WJ Finkenzeller,ME Thompson,H Yersin - 《Chemical Physics Letters》 被引量: 35发表: 2007年 ...
This small substitution was found to have a profound effect on the photophysical properties, red-shifting the emission profile from 595 nm in the case of [Os(28)2](PF6)2, to 650 nm in MeCN. Since the btp ligands constitute the LUMO of these complexes in the 3MLCT state, the ...

Different sites due to different environments of Ir(btp) 2(acac) show dissimilar intensity distributions of the substate emissions, zero-field splittings, emission decay times, and spin-lattice relaxation (SLR) times. Temperature dependent investigations of the SLR processes reveal the importance of ...
