Regarding the magnetic properties of the C-G hybrids, the unpaired electrons can be distributed within the whole system, including the graphene platform. Indeed, the spin density surface of C-G hybrids is mainly allocated on both copper corroles and the edge of the graphene nanosheet (Fig. ). Indeed, spin density delocalization/polarization mechanism is present in all the cases that agree with other studies, especially for graphene nanoribbons indicating that electronic structure is in line with experimental evidence .
