✦ Synopsis

A new water-soluble calix[4]arene-based bipyridyl podand was prepared by incorporation at the upper rim of four phosphonate 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
