Fabrication of H2TPyP-based nanostructures via an oil/water medium. (A) Molecular structures of 5, 10, 15, 20-tetra(4-pyridyl)-21H, 23H-porphine (H2TPyP) and cetyltrimethylammonium bromide (CTAB). (B), (C) Self-assembly process via an oil/water medium, where (B) shows the original transparent CTAB aqueous solution and (C) indicates the addition of a H2TPyP chloroform solution to a CTAB aqueous solution. (D) Solution obtained after stirring is maintained for 15 min.
