Negishi reactions of 3-halogen and 3,5-dihalogen substituted BODIPYs with different organozinc reagents are reported as the first examples of this valuable palladium-catalyzed C–C coupling reaction into the family of the BODIPY dyes. It is demonstrated that the Negishi coupling is especially useful for obtaining interesting alkylated BODIPYs, including synthetically-valuable asymmetrically-3,5-disubstituted

A novel metal ion-sensitive fluorescentprobe – 4,4-difluoro-8-(4-methylphenyl)-5-(phenylethynyl)-3-[bis(pyridin-2-ylmethyl)amino]-4-bora-3a,4a-diaza-s-indacene – based on the BODIPY platform with di(2-picolyl)amine as chelator has been synthesized and spectroscopically and photophysically characterized. The generalized treatment of the solvent effect shows that solvent dipolarity is primarily responsible
