| Description | 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. |
