Abstract

Recentry, we reported that Carbazole dendrimers with metal assembling phenylazomethine core has efficient Hole-transfer property [1]. We synthesized new porphyrin core azomethine-carbazole hybrid Dendrimers without Ullmann reaction. The fluorescence spectrum shows that the dendron works as a light harvesting antenna. New dendrimer successfully assemble metal, and crosslinks with UV irradiation. EL devices were fabricated by spin coating ZnP-DPA-CbzG2, and vacuum evaporating Alq₃ (tris-8-hydroxyquinoline aluminum): ITO/ZnP-DPA-CbzG2/Alq₃/CsF/Al, where ZnP-DPA-CbzG2 acts as Hole-transporting layer (HTL), and Alq₃ as Emitting Layer (EML). ZnP-DPA-CbzG2 showed efficient hole-transfer properties. The starting voltage was 3.0V(0.01 Cd/m²), and the maximum luminescence was over 6000 Cd/m² (at 11V).
