J-Aggregation of protonated meso-tetrakis(sulfonatothienyl)porphyrin isomers: Morphological selection of self-assembled nanostructures from structurally similar zwitterionic porphyrins

Morphological selection of the self-assembled nanostructure of zwitterionic porphyrins between nanorod and nanosheet by the small displacement of the peripheral anionic position is demonstrated based on the J-aggregates of zwitterionic porphyrin isomers, meso-tetrakis(5-sulfonatothienyl) porphyrin diacid and meso-tetrakis(4-sulfonatothienyl) porphyrin diacid.
