Phosphorescence of iridium(III) complexes with 2-(2-pyridyl)-1,3,4-oxadiazoles

Cationic bis-cyclometalated iridium(III) complexes [(C boolean AND N)(2)Ir(N boolean AND N)](PF6) with 2-(2'-pyridyl)-5-R-1,3,4-oxadiazoles (N boolean AND N; R = 1-adamantyl, mesityl, N-diphenylamino) have a redox gap of 2.58-2.68 V and exhibit orange-red phosphorescence in argon-saturated dichloromethane solution with a maximum, quantum yield, and excited-state lifetime of 613-644 nm, 2-6%, and 90-280 ns.
