Description Covalently linked BF2-oxasmaragdyrin-BODIPY and BF2-oxasmaragdyrin-ferrocene dyads were synthesized by coupling of meso-triaryl oxasmaragdyrin containing meso-iodophenyl group with meso-(p-ethynylphenyl) borondipyrromethene and alpha-ethynyl ferrocene respectively under mild Pd(0) coupling conditions. NMR, absorption and electrochemical studies indicated that the two moieties in the dyads retain their individual characteristic features. The fluorescence studies indicated a possibility of photoinduced singlet-singlet energy transfer from BODIPY unit to BF2-oxasmaragdyrin unit in BF2-oxasmaragdyrin-BODIPY dyad and photoinduced electron transfer from ferrocene unit to excited state of BF2-oxasmaragdyrin unit in BF2-oxasmaragdyrin-ferrocene dyad.
