Room temperature phosphorescence from a platinum(II) dilmine bis(pyrenylacetylide) complex
Room temperature phosphorescence has been observed in a synthetically facile Pt(II) complex, Pt(dbbpy)(CdropC-pyrene)(2) (dbbpy = 4,4'-di(tert-butyl)-2,2'-bipyridine; CdropC-pyrene = 1-ethynyl-pyrene), in fluid solution. The static and time-resolved absorption and luminescence data are consistent with phosphorescence emerging from the appended C-c-pyrenyl units following excitation into the low energy dpi Pt --> pi* dbbpy metal-to-ligand charge transfer absorption bands.
