A bifunctional calixarene designed for immobilisation on a natural polymer and for metal complexation

The present work describes the multi-step synthesis of a new bifunctional calix[4]arene designed for grafting on natural polymeric materials, such as water-soluble dextrans, and for metal complexation. The podand was then anchored to the polymer by means of a cyanuric linker. The resulting material showed an interesting ability to complex copper(I), giving stable yellowish light orange solids and aqueous solutions.
