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

Abstract

AbstractA 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.
