[17a-PA04-1] Development of Carbazole-Triazine Dendrimer TADF Materials with Bulky Substituents
Keywords:Dendrimer, Thermally activated delayed fluorescence, Carbazole
Recently, carbazole-triazine dendrimers with various substituents and generations have been reported. in order to suppress concentration quenching, second-generation dendrimers with three bulky substituents, adamantyl, tetraphenylphenyl, and phenylfluorene, were synthesized and their properties were measured. The dendrimer with phenylfluorene exhibited the highest PLQY of 81% in neat films and the highest reverse intersystem crossing rate constant.
