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

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...

Sumario: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)(2)acac (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)].
