N2  - The preparation and spectroscopic properties of a quaternary pyridinium porphyrin containing ethoxycarbonylmethyl groups are described. Partial saponification of the ester groups yields a series of mixed ester/carboxylate salts which show evidence of strong intermolecular association in aqueous solution. The fully saponified tetracarboxylate inner salt was prepared in high yield and has properties which conflict with a previous report.
