Phosphorescent Ir(III) complexes are promising luminophores as they possess good photostability, high phosphorescence quantum efficiency, relatively short phosphorescence lifetimes, facile color tunability, and large cross-section for the exciton formation. Such favorable features prompted the development of a number of novel phosphorescent Ir(III) complexes for the application in novel utilities, including electrophosphorescence, biological labeling, sensitizers for charge-transfer reactions in DNA, photocatalysts for water splitting reactions, and singlet oxygen sensitization. This talk covers recent reults on four projects: 1) Phosphorescence color tuning by employing an excited-state interligand energy transfer, 2) wide bandgap host materials for blue electrophosphorescence, 3) high efficiency dendritic Ir(III) complexes, and 4) functional phosphorescent Ir(III) complexes exhibiting sensing capability, photochromic on/off switching, enhanced phosphorescence in solid state. |
