Dibenzo[c,g]indolo[3,2,1-jk]carbazole as a new chromophore for blue organic light-emitting diodes

Author affiliations

Abstract

A novel sky-blue fluorescent emitter was developed from a novel dibenzo[c,g]indolo[3,2,1-jk]carbazole chromophore. A photoluminescence quantum yield of 94.1%, maximum quantum efficiency of 6.2%, high luminance over 80 000 cd m−2, and 4.8 times extension of the operational lifetime compared to that of a pyrene derived blue emitter were realized from the fabricated device.
