摘要：

The fluorescent molecules 7,7-dimethyl-N,N-diphenyl-7H-indeno[1,2-a] phenanthren-9-amine (DIP) and 4-(7,7-dimethyl-7H-indeno[1,2-a]phenanthren-9-yl)-N,N-diphenylaniline (TIP), with indenophenanthrene cores and attached arylamine structures, were synthesized for use as extremely deep blue fluorescent emitting materials. A non-doped device using DIP as an emitting material exhibited a maximum external quantum efficiency of 3.27% and had Commission Internationale de l'Eclairage (CIE) color coordinates of (0.158, 0.040).
