The formation of a novel porphyrin colloidal structure has been investigated-so called microneedles. The porphyrin colloids consist of the tetravalent anionic tetra-(4-sulfonatophenyl)porphyrin (TPPS) and the tetravalent cationic tetra-(N-methyl-4-pyridyl)porphyrin (TMPyP), forming ionic organic solid particles in ethanol. The structure dependence on various influences such as ratio of TMPyP to TPPS, the time of mixing, different solvent mixtures, and the metalation of one porphyrin is investigated with UV-Vis spectroscopy, zeta-potential, light microscopy, and transmission electron microscopy (TEM). The light harvesting potential of the microneedles is demonstrated as a proof of concept by the catalytic degradation of Rose Bengal.
