, p. 14301 - 14305 (2019)
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 80000 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.

PROBLEM TO BE SOLVED: To provide a synthesis method that increases the yield of an organic compound having a fused carbazole skeleton. SOLUTION: In synthesis of an organic compound having a fused carbazole skeleton, the chlorine content in a compound having a fused carbazole skeleton used as an ingredient is made 10 ppm or less thereby allowing increase of the yield of the organic compound having the fused carbazole skeleton.
