Novel porphyrin based receptors for saccharide recognition in water

A binding study of the porphyrin phosphonates (1, 2), porphyrin–oligopeptide conjugates (3–5) and meso-tetrakis-(p-sulfonato-phenyl) porphyrin (7) to saccharides and alkyl pyranosides showed strong interaction in water and DMSO. The 1H, 31P NMR, IR-spectroscopy and SPR technique were used for the study of mechanisms of complexation and potential using of receptors as sensor part; participant of hydrogen bonds in porphyrin–saccharide complexes formation was demonstrated.
