Both metalloporphyrins and N-Heterocyclic carbenes (NHCs) have been extensively studied as photosensitizers for organic photovoltaics. In this work the geometric and electronic properties of the first manganese(II) porphyrin carbene complexes are revealed, and compared with the cyanide and imidazole analogues which suggest the similarities and differences of the ligands. The work would deepen understanding on these species and facilitate their applications in related fields.
