Triphenylamine-imidazole-based luminophores for deep-blue organic light-emitting diodes: experimental and theoretical investigations

Abstract

Solution-processable multilayer OLEDs were fabricated by employing the blue luminophores as dopants in the 4,4′-bis(9<italic>H</italic>-carbazol-9-yl)biphenyl (CBP) host and were found to exhibit bright deep blue electroluminescence with high efficiency.
