Recently, Coordination polymer gels (CPGs) have been exploited for their metal ions which have been reported to show unusual functional properties, such as redox responsiveness, catalysis, phosphorescent behaviour, spin-crossover phenomenon. Furthermore, by selectively binding metal ions to gelator molecules one can affect self-assembly modes and finely tune gelation conditions. Much like in supramolecular chemistry, chemists have begun to rationally design CPG ligands and gelators with suitable coordination geometries for the incoporation of specific metals to generate scaffold containing void spaces. These cavities amongst the polymers can thus accommodate additional solvent molecules in the gel state. I will present the preparation and applications of gels formed from the functional calix[4]arene-based ligand and metal ions to sensing, drug-delivery and catalysis that have been developed over the past five to seven years. Calix[4]arene-based ligands include pyridine, tetrazole, carboxyl acid and amino acid moieties which bind to metal ions to form coordination polymer gels in organic solvents or water, and are characterized by their indiscrete structure which self-assemble to form fibrillar networks.
