Abstract

Here we report the synthesis and electrophosphorescence of a new deep-red phosphorescent Ir (III) complex with spatially embracing and thus solubilizing arylsilyl- substituted ligands, Ir (III) tris (2-(2'-benzo [b] thienyl)-5-(4'-triphenylsilylphenyl) pyridinato-N, C 3'). A poly (N-vinylcarbazole)(PVK) film doped with this Ir (III) complex exhibited excellent phase homogeneity and showed saturated red electrophosphorescence of 2.7% ...
