A novel doped EL device was fabricated utilizing thermal ring closure reaction of 3, 3′-dibenzanthronyl (1) in the vacuum deposition process. By controlling deposition temperature of (1), part of (1) reacted to violanthrone (2) to give a thin film of compound (1) doped with (2). Red emission of (2) was observed from the EL cell consisted of ITO/TPD/(1) doped with (2)/Al.
