Abstract:
A heterotritopic copillar[5]arene monomer by introducing effective neutral guest moieties (methylene chains end-capped with cyano and triazole groups) to a pillar[5]arene macrocycle is prepared. This well-designed AB2 -type copillar[5]arene contains strong host-guest recognition motifs that are connected with relatively flexible and long linkers, thus efficiently assembles to form supramole-cular hyperbranched polymer (SHP) in chloroform solution, which is characterized by various techniques including (1) H NMR, DOSY, viscosity, DLS, and TEM. Particularly, this supramolecular polymer can be effectively depolymerized by adding a competitive butanedinitrile guest.
