Abstract

A calix[4]arene(cone)-capped tetraphenylporphyrinatozinc (2-Zn) in which two distal-phenyl p-positions in calix[4]arene are linked to two distal mesophenyl groups in tetraphenylporphyrinatozinc was synthesized via 12 steps. This calix[4]arene-porphyrinatozinc conjugate showed a high affinity toward a guest molecule, C-(1-methylpyridinium-4-methylamino)-L-isoleucine owing to a cooperative action of the cation-π interaction between the calix[4]arene cavity and the 1-methylpyridinium moiety and the coordination of the amino group to Zn(II).
