• unsymmetrical porphyrins
• meso-alkyl substituents
• meso-pyridyl substituents
• octanol/water coefficients

The synthesis of one-step meso-porphyrins type A(x)B(y) containing alkyl and pyridyl groups is described. An initial assess of the amphiphilic proprieties were determined by its log K-ow using fluorescence detection techniques and values from 1.42 to 2.15 were observed. The melting points of this set of porphyrins was determined and a strong effect of the number and size of the meso-alkyl chain is ascribed.
