1,7-isoxazolyl Substituted BODIPY Dyes – Synthesis and Photophysical Properties

A range of novel BODIPYs with the isoxazolyl groups at 1,7-positions were prepared from 3-(4-chlorophenyl)-5-(5-phenyl-1H-pyrrol-3-yl)isoxazole and their photophysical properties were characterized. The presence of the isoxazolyl groups at 1,7-positions, shifts long-wavelength absorption at 581±4 nm and emission at 622±3 nm in the near-infrared region. A comparison of three variants of substituents at positions 1,7 of BODIPY core is shown. © 2023 Wiley-VCH GmbH.
