Stimuli‐Responsive Molecularly Imprinted Polymers: Mechanism and Applications.

Molecularly imprinted polymers (MIPs) are very suitable for extraction, drug delivery systems, and sensors due to their good selective adsorption ability, but the difficulty of eluting templates during synthesis and the limitation of application scenarios put higher demands on MIPs. Stimuli‐responsive MIPs (SR‐MIPs) can actively respond to changes in external conditions to realize various functions, which provides new ideas for the further development of MIPs. This paper reviews the multiple response modes of MIPs, including the common temperature, pH, photo, magnetic, redox‐responsive and rare gas, biomolecule, ion, and solvent‐responsive MIPs, and explains the mechanism, composition, and applications of such SR‐MIPs. These SR‐MIPs and the resulting dual/multiple‐responsive MIPs have good selectivity, and controllability, and are very promising for isolation and extraction, targeted drug delivery, and electro‐sensor.
