✦ Synopsis

Introduction of one or two 2,2'-bipyridine units at the upper rim of the calix[4]arene platform was performed by means of the Wittig reaction. The resulting alkenes were hydrogenated to give two new bipyridyl-based calixarene podands, which were studied as ligands for Co II cation. The mono-bi-
