| 中文摘要 | by fusing an electron-deficient ring system with the phenyl ring of a 2-phenylpyridine (ppy)-type ligand, a new and synthetically versatile strategy for the phosphorescence color tuning of cyclometalated iridium(iii) and platinum(ii) metallophosphors has been established. two robust red electrophosphors with enhanced electron-injection/electron-transporting features were prepared by using an electron-trapping fluoren-9-one chromophore in the ligand design. the thermal, photophysical, redox and electrophosphorescent properties of these complexes are reported. these exciting results can be attributed to a switch of the metal-to-ligand charge-transfer (mlct) character of the transition from the pyridyl groups in the traditional ir-iii or pt-ii ppy-type complexes to the electron-deficient ring core, and the spectral assignments corroborate well with the electrochemical data as well as the timedependent density functional theory (td-dft) calculations. the electron-withdrawing character of the fused ring results in much more stable mlct states, inducing a substantial red-shift of the triplet emission energy from yellow to red for the ir-iii complex and even green to red for the ptii counterpart. |
