Abstract

We investigated photoluminescence (PL) and electroluminescence (EL) characteristics of 3,3′-dicyano-[7,7′-biindoli-zine]-1,1′,2, 2′-tetracarboxylic acid 1,2-diethyl 1′,2′-dimethyl ester (Et2Me2-biInd). We found that Et ₂Me ₂-bilnd has efficient blue PL and a multilayer organic light-emitting diode doped with Et ₂Me ₂-biInd exhibits a relatively high EL efficiency of 1.8 ±0.1%.
