摘要：
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 (eta(ex)) -24.8%; current efficiency (eta(c)) -57.1 cdA(-1); power efficiency (eta(p)) -64.8 lmW(-1) with Commission Internationale de l'Eclairage (CIE:0.49, 0.40) than NDBNPIN:Ir(MDQ)(2)acac (4%) device [eta(ex) - 23.1%; eta(c) -54.6 cdA(-1); eta(p) - 60.0 lm W-1 with CIE (0.47, 0.42)].
