Effective Modulation of 2,1,3-Benzothiadiazoles and 2,1,3-Benzoselenadiazoles Photoluminescence Properties by Pd-Catalyzed C–H Bond Arylations

Abstract

A one step procedure towards 4-aryl-2,1,3-benzothiadiazoles, 4,7-diaryl-2,1,3-benzothiadiazoles and 4-aryl-2,1,3-benzoselenadiazoles using palladium-catalyzed regioselective C–H bond arylations of 2,1,3-benzothiadiazole and 2,1,3-benzoselenadiazole was developed. A donor–acceptor compound was also synthetized via two successive C–H bond arylations at C4 and C7 positions of the 2,1,3-benzothiadiazole unit. One of the major achivement of this methodoly refer from the fine modulation of the fluorescence wavelength with emission colors covering the blue to the red part of the visible spectrum by the simple introduction of the suitable aryl group on the 2,1,3-benzothiadiazole unit.
