Synthesis, crystal structure, and photophysical properties of mononuclear and dinuclear palladium BODIPY chromophores

Mononuclear and dinuclear palladium-centered boron dipyrromethene (BODIPY) complexes, HBDPPdI and BDPPd2I2, respectively, were synthesized by the direct insertion of a palladium source into iodine-substituted BODIPY chromophores. The molecular structures of both metal complexes were characterized using several analytical techniques, including single crystal x-ray diffraction, to find that Pd(0) is coordinated directly to the ligand through a Pd-C bond facilitated by the insertion reaction. The photophysical properties of these complexes were also detailed.
