Synthesis, Luminescence, and Electrochemistry of Tris-Chelate Platinum(IV) Complexes with Cyclometalated N-Heterocyclic Carbene Ligands and Aromatic Diimines.

ABSTRACT: Dicationic, C₂-symmetrical, tris-chelate Pt(IV) complexes of general formula [Pt(trz)₂(N∧N)](OTf)₂, bearing two cyclometalated 4-butyl-3-methyl-1-phenyl-1H-1,2,3-triazol-5-ylidene (trz) ligands and one aromatic diimine [N∧N = 2,2'-bipyridine (bpy, 2), 4,4'-di-tert-butyl-2,2'-bipyridine (dbbpy, 3), 4,4'-dimethoxi-2,2'-bipyridine (dMeO-bpy, 4), 1,10-phenanthroline (phen, 5), 4,7-diphenyl-1,10-phenanthroline (bphen, 6), dipyrido[3,2-a:2',3'-c]phenazine (dppz, 7), or 2,3-diphenylpyrazino[2,3-f][1,10]phenanthroline (dpprzphen, 8)] are obtained through chloride abstraction from [PtCl₂(trz)₂] (1) using AgOTf in the presence of the corresponding d
