The incorporation of stimuli-responsive molecular functionalities within the receptor sites of rigid polymer materials generated by molecular imprinting is a new approach for the fabrication of stimuli-responsive materials (SRMs). The objective of this project is to develop a new series of photoresponsive molecularly imprinted SRMs that are operational in aqueous media. The researchers’ previous studies have shown that polymer-bound functionalized azobenzenes may lose their photoisomerizibility in aqueous media if the polymerizable functionality and the guest-binding moiety are located on different aromatic rings of the azobenzene chromophore. In this project, new water-compatible MIP materials from a series of new azobenzene functional monomers with both the polymerization and guest-binding functionalities located on the same aromatic ring will be fabricated and studied for their photoresponses in aqueous media. Structural features of these new azobenzene functional monomers and the imprinting conditions will be optimized for the photo-regulated release and uptake of selected molecular guests. Results obtained from this project will be useful to the development of SRMs for controlled drug delivery, phototherapy, and other advanced stimuli responsive applications. </P
