Deep blue thermally activated delayed fluorescent emitters using CN modified indolocarbazole as an acceptor and carbazole derived donors

Abstract

Deep blue thermally activated delayed fluorescent (TADF) emitters having carbazole derivatives as donors and CN modified indolocarbazole as an acceptor were developed. Indolocarbazole moiety modified by CN was an acceptor of the all carbazole based TADF emitters, and carbazole and t-butylcarbazole were donors combined with the CN modified indolocarbazole. The all carbazole based TADF emitters showed narrow emission spectrum with a less than 60 nm full width at half maximum, deep blue emission color with a y color coordinate below 0.13, and a high external quantum efficiency of 16.0%.
