Özet

The first imine-bridged meso-meso-and beta-meso-linked porphyrin-corrole dyads were prepared, and their photo-physical properties were investigated by UV/Vis and fluorescence spectroscopy. To gain more insights into the geometric structures and the frontier molecular orbitals of the newly synthesized structures, DFT calculations at the B3LYP/6-311G(d, p) level in the gas phase and with toluene as the solvent were performed. The theoretical results indicate that the imine-bridged dyads possess well-defined charge separation between the porphyrin and corrole moieties; therefore, intramolecular electron transfer from the corrole to the porphyrin ring is favoured.
