Highly emissive planarized B,N-diarylated benzonaphthoazaborine compounds for narrowband blue fluorescence.

ABSTRACT: Highly fluorescent blue emitters with high color purity are of great significance for optical applications. Herein, a series of planarized B,N-diarylated benzonaphthoazaborine compounds, namely, BzNp (1), BuBzNp (2), Bu₂BzNp (3), Bu₂BzMeNp (4), and Bu₂BzBuNp (5), where electron-donating ^t Bu and Me groups are differently introduced into the B-Ph, N-Ph, or benzoazaborine rings, are prepared and characterized. All compounds exhibit low-energy absorptions (λ _abs = 462-467 nm) and emissions (λ _PL = 472-478 nm) remarkably red-shifted compared with those found for the pristine dibenzoazaborine compound (404 and 415 nm, respectively). Although the expansion of π-conjugation in the az
