Abstract

Here we report the synthesis and characterization of cyclometallated iridium complex which emits sky-blue light. The hybrid meso-structured nanocomposites by sol-gel co-assembly with tetraethyl ortho-silicate and corresponding molecular interactions within mesopores were also demonstrated. Electroluminescent devices were fabricated using carbazole-based monomer and iridium complex as active layer, which act as host/guest system through co-assembled sol-gel process. Devices based on this nanocomposite showed improved luminescent efficiencies several times higher than that of similar chromophore elaborated in the literature. The designed chromophoric amphiphiles can act as photonically active materials as well as structure-directing agents.
