Triphenylamine-based N,O-bidentate BF₂ complexes: synthesis and photophysical properties

Abstract

N,O-bidentate BF2 dyes (TTBKI-1 and TTBKI-2) with D–π–A structures were designed and synthesized by combining an electron-donating triphenylamine unit, a π-conjugated thiophene unit, and an electron-accepting NBF2O moiety.
