Herein, a series of blue-emitting Ir(III) phosphors is reported based on the cyclometalating N-heterocyclic carbenes (NHCs), in which typical benzimidazolylidene entity now replaced by new 7,9-dihydro-8H-purin-8-ylidene unit. The two extra-nitrogen atoms that are successfully fined turn emission to true-blue region. As proof concept, both experimental measurement and theoretical calculation the...
