Abstract

Abstract : Three 1 H -pyrazolo[3, 4- b ]quinolines (PQs) with N, N -diarylamine moiety were synthesized. They were used as dopants in poly(9- N -vinylcarbazole) (PVK) matrice. An additional star burst oligoquinoline TRI-Q electron transporting layer was deposited on emission layer from solution. The devices with configuration ITO/PEDOT:PSS/PVK-PQ/TRI-Q/Ca/Al show bright green emission with luminance L = 355–806 cd m −2 .
