Multiresponsive Supramolecular Gel Based on Pillararene-Containing Polymers
A multiresponsive supramolecular
gel was constructed based on a
bisÂ(pyridinium) dication guest and a copolymer with pillararenes as
the pendant groups, which was synthesized by free radical copolymerization
of methacrylate-functionalized pillararenes and methyl methacrylate.
The mechanism of gel formation was explored by the intensive study.
Upon addition of competitive host or guest molecules, pillararene-based
gel could be transferred into sol due to the competition of host–guest
complexation. Surprisingly, the ordered stacking of pillararenes was
indispensable to obtain the supramolecular gel, which endowed the
system with response to temperature change
