carboxyl acid structures were prepared. Gelation behaviours of the compounds and calix[4]arene itself in ten common organoalkoxysilanes were studied. It was found that at a concentration of 2% (w/v), only the compound with the most carboxyl groups (CTA) functions as a gelator, and only this compound gels with three of the liquids tested; however, the as created gels possess smart thixotropic and thermo-reversible
