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 SNAr. The fluorophores show interesting tunable optical properties associated with the formation of a twisted intramolecular charge transfer excited state and competing intersystem crossing.

We recently reported on the synthesis of several 3-chalcogen substituted BODIPYs, which exhibit intersystem crossing (ISC) quantum yields comparable to those of iodo-analogues.[20]
