Synthesis and properties of chiral amide-bonded porphyrin dimers with various functional bridging blocks

Low Symmetric meso-Borneol and meso-Carbazole Substituted H3Corroles: Synthesis, Characterization and Their Anticancer Behaviors

“…Porphyrins, a group of highly conjugated heterocyclic macrocycle organic compounds, composed of four modified pyrrole subunits interconnected at their α carbon atoms have been investigated in various fields during past decades. [1][2][3][4] Corroles are important porphyrin derivatives that provide sterically constrained environments for coordinating central cations, since in contrast with porphyrins they have three inner N−H protons to maintain the heteroaromatic properties of the ligand π-system in the presence of only three mesocarbons. [5][6][7] Various functional groups can be introduced at the meso-, β-, and/or axial positions to modify the structures of the corrole ligands and their metal complexes.…”
