A novel hot exciton blue fluorophores and white organic light-emitting diodes with simplified configuration.

ABSTRACT: The two efficient non-doped blue emitters with hybridized local and charge transfer state namely, NDBNPIN and DBTPIN have been synthesised and characterised. These materials are employed as a host for green and red phosphorescent OLEDs. The white device based on DBTPIN:Ir(MDQ)₂(acac) (4%) exhibit maximum external quantum efficiency (η_ex) -24.8%; current efficiency (η_c) -57.1 cdA^-1; power efficiency (η_p) -64.8 lmW^-1 with Commission Internationale de l'Eclairage (CIE:0.49, 0.40) than NDBNPIN:Ir(MDQ)₂acac (4%) device [η_ex - 23.1%; η_c -54.6 cd A^-1; η_p- 60.0 lm W^-1 with CIE (0.47, 0.42)].
