A new water-soluble calix [4]arene-based bipyridyl podand was prepared by incorporation at the upper rim of four sulphonate groups; the association of its hydrophilic and chelating properties was positively evaluated in the complexation of copper(I) in water.

## Abstract A water‐soluble calix[4]arene‐based podand has been prepared by incorporation, at the lower rim, of two 4,4′‐dicarboxy‐2,2′‐bipyridine units in opposite positions. The association between its coordination and hydrophilic properties were beneficial to the complexation and solubilization
The coordination of a water molecule, bridging two distal phenolate anions of the tetrasulphonated calix[4]arene 1,3-dicarboxylic acid, has a remarkable influence on the acid base and inclusion properties of the ditopic receptor.
