Triphenylpyrazine: methyl substitution to achieve deep blue AIE emitters

Abstract

Based on our deep comprehension of the unique excited state decay process of tetraphenylpyrazine derivatives, triphenylpyrazine-3-carbazole (TrPP-3C) was designed by replacing the phenyl group with a methyl group at the 3-position of pyrazine. Compared to the values for its model tetraphenylpyrazine-3-carbazole (TPP-3C), the Commission International de l’Eclairage (CIE) coordinates of TrPP-3C shifted to the more valuable deep-blue region in the non-doped device, demonstrating that the in-depth study of the excited state distribution was of great significance for the development of a new aggregation-induced emission (AIE) building block.
