Preparation and characterization of a new meso-substituted tetrapyrrole macrocyclc: Meso-tetra[2-(3-carboxyethyl)furyl]porphine, [TFP]

The preparation of meso-substituted tetrafuryl-porphines is described. These new compounds are very soluble either in organic solvent or in water depending upon the furyl groups substitution. Their spectroscopic absorption, nmr characteristics, and some of their electrochemical properties are reported.
