Carbazole dendrimers have a head-to-tail type molecular structure and unique polarized electronic structure with HOMO localized in the outer layer and LUMO localized in the inner layer. This electronic structure matches the design principle of thermally activated delayed fluorescence (TADF) materials. TADF materials are attracting attention as third-generation OLED materials and we have reported the first solution processable TADF dendrimer based on the carbazole dendrimer donor. Most recently, we found that carbazole dendrimerization is also effective in improving the efficiency of doublet (radical) luminescent materials, which are fourth-generation OLED materials. In this talk, we will introduce the design of light-emitting materials for OLEDs based on carbazole dendrimers.
