Synthesis and fluorescent properties of some benzothiazole derivatives synthesized via Suzuki cross coupling reaction

Abstract

Fifteen compounds containing benzothiazole have been synthesized successfully via Suzuki reaction of 2-(4- bromophenyl)benzothiazole 1 and phenylboronic acid derivatives in high yield. All samples display fluorescence emissions at wavelengths in the range of 380 to 450 nm under the excitation light of 330 nm. Compounds 2d, 2e, 2h and 2k exhibit quite good fluorescent property.
