Abstract

The porphyrin–crown ether derivatives described here exhibit affinities to unprotected peptides of hitherto unknown magnitude in aqueous solution; the optical signal built-in to porphyrin receptors makes these applicable also to sensor techniques; the results can also form the basis of new catalytic systems, e.g. for the catalytic oxidation of peptides (such as tyrosinase models).

  5. Amino acids and peptides form complexes with 18-crown-6 with low to moderate constants, depending on the nature of the solvent medium (R. M. Izatt, P. Krystyna and J. S. BradshawChem. Rev., 1991, 97, 1721). Typical logK values in MeOH for the association of Gly-Phe and Ala-Met with 18-crown-6 are 3.5 and 1.75 M–1, respectively (V. A. Bidzilya, L. P. Golovkova and K. B.
