Porphyrinoids are considered perfect candidates for
their incorporation into electron donor–acceptor (D–A) arrays
due to their remarkable optoelectronic properties and low
reorganization energies. For the first time, a series of
subphthalocyanine (SubPc) and corrole (Cor) were covalently
connected through a short-range linkage. SubPc axial substitution strategies were employed, which allowed the synthesis of the target molecules in decent yields. In this context, a qualitative synthetic approach was performed to reverse
the expected direction of the different electronic events.
Consequently, in-depth absorption, fluorescence, and electrochemical assays enabled the study of electronic and photophysical properties. Charge separation was observed in cases
of electron-donating Cors, whereas a quantitative energy
transfer from the Cor to the SubPc was detected in the case
of electron accepting Cors
