Synthesis of Copillar[5]arene by Co‐oligomerization of Different Monomers and Its Application to Supramolecular Polymer Gel

Abstract

Abstract A copillar[5]arene derivative with different repeating units was synthesized by co‐oligomerization of different alkyl ethers. Copillar[5]arene‐based supramolecular polymer gel was formed by a self‐inclusion complexing in acetonitrile. The supramolecular polymer gel was driven by the CH· π interactions, and presented two phases as time went on, and finally, constructed the supramolecular organic framework. Notably, the supramolecular polymer gel showed reversible gel‐sol phase transitions upon heating and cooling. Meanwhile, the transparent films formed by the supramloecular gel show the potential application in the field of anti‐acid rain materials.
