2‐Aza‐21‐Carbaporphyrin in Construction of Chiral Supramolecular Assemblies

Complexes of N‐Confused Porphyrin Derivatives as Ortho‐Metallating Ligands. Synthesis, Structure, Redox Properties, and Chirality

“…The crystal structures reveal roughly the same orientation of the chloride ligand at the external metal center and the substituent at C21. Thus, the chirality of the bimetallic monomers in the solid state and solution is predefined by the starting metalloligands [ 43 , 44 ] with absolute configurations S or R at C21 in the metalloligands invariantly giving rise to the configurations P or M , respectively in the ortho ‐metallated complexes. The separation of the bimetallic enantiomers by the HPLC method was expected to be effective through two approaches ( Scheme 2 ).…”
