The first imine‐bridged meso – meso ‐ and β‐ meso ‐linked porphyrin–corrole dyads were prepared, and their photophysical 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.
