Photoluminescence and Electroluminescence Characteristics of 3,3'-Dicyano-[7,7'-biindolizine]-1,1',2,2'-tetracarboxylic Acid 1,2-Diethyl 1',2'-Dimethyl Ester

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