题目: Transition Metal Based Phosphors with Novel Chromophoric Chelate(s)
地点：909号楼一楼B会议室(Conference Room B, 909-1F)
Luminescent Os(II), Ir(III) and Pt(II) metal complexes, particularly those with chelating cyclometalates, play a key role in the recent development of optoelectronic technologies such as organic light emitting diode (OLED). The attraction of these complexes comes from their higher chemical stability due to the strong metal-ligand bonding interaction, as well as the longer excitation lifetimes and higher emission quantum yields. As a result, syntheses of these metal complexes bearing cyclometalate and relevant chromophoric chleates were extensively examined. In this presentation, the development of new phosphorescent metal complexes, particularly those constructed with functionalized pyridyl azolate, biazolate and 2,6-dipyrazolyl pyridine fragments, will be elaborated in a systematic manner.
