Abstract

Abstract : Novel 2-chalcogen- or 2, 6-dichalcogen-BODIPY derivatives were synthesized by a Pd-catalyzed C–heteroatom Stille cross-coupling reaction, overcoming the limitations of SN Ar. Abstract : Seven new 2-chalcogen- or 2, 6-dichalcogen- (S, Se, Te) BODIPY derivatives were synthesized in good to excellent yields (55–95%) by a Pd-catalyzed C–heteroatom Stille cross-coupling reaction, overcoming the limitations of SN Ar. The fluorophores show interesting tunable optical properties associated with the formation of a twisted intramolecular charge transfer excited state and competing intersystem crossing.
