000189410 520__ $$aCationic cyclometalated iridium(III) complexes [(N,C-2'-2-phenylpyridyl)(2)Ir((NN)-N-boolean AND)](PF6) with alkyl-substituted 1-(2'-pyridyl)-pyrazole (NN)-N-boolean AND ligands exhibit green phosphorescence from a cyclometalating-ligand-centered excited state with structured emission spectrum and with quantum yield and excited-state lifetime of up to 26% and 1.4 mu s in argon-saturated dichloromethane solution. The alkyl groups do not change the energy or the nature of the emissive state; however, those alkyl groups that hinder coordination of the (NN)-N-boolean AND ligand to iridium(III) strongly quench phosphorescence of the complex.
