Abstract:
[structure: see text] A switchable, supramolecular polymer is introduced which is held together through hydrogen bonding and reversibly precipitates-redissolves upon subtle pH control. Precipitating, it entraps and stores guest molecules within the self-assembling capsules incorporated within the polymeric chain.
