  • Unique Photoluminescence Behavior of Phosphorescent Organoplatinum(II) Complexes

    Prof. Shigeyuki Yagi,   Department of Applied Chemistry, Graduate School of Engineering, Osaka Prefecture University, Japan

    Phosphorescent organoplatinum(II) complexes adopt four-coordinated square planar geometry and sometimes show unique luminescence behavior based on the excimer or aggregate formation through intermolecular Pt-Pt interaction. In the present talk, two topics will be provided on phosphorescence properties of our organoplatinum(II) complexes : one is the substituent effect on the excimer emission of (ppy)Pt(acac)-type complexes (ppy and acac; 2-phenylpyridinate and acetylacetonate, respectively), and the other is the luminescent mechano- and vapochromic behavior of solid-state (C^N^C)PtX-type complexes (C^N^C and X; 2,6-duphenylpiridine tridentate ligand and neutral monodentate ligand, respectively).
