4-Difluoro-4-bora-3a,4a-diaza-s-indacene(BODIPY) derivatives are becoming increasingly popular because BODIPY dyes possess desirable chemical and photostability attributes,relatively high absorption coefficients and fluorescence quantum yields,and contain narrow absorption and emission bands with high peak intensities.Conjugated polymers with BODIPY derivatives in the backbone were characteristic with an absorption maximum wavelength above 550 nm and emission maxima ranges from orange to the near-infrared region.Herein,a new BODIPY-containing conjugated polymer(P1) had been designed and synthesized as a colorimetric and fluorescent chemosensor for F-and CN-.
