| Research Abstract |
We developed a material system composing of stimuli responsive polymer and super molecules. Those combination enable us to achieve a chiral separation by slight temperature change. The super molecules, such as chiral crown ether (CC) or cyclodextrine (CD) can recognize guest molecules as its chirality, and thermo responsive polymer can change their complex constant by changing its volume. Chiral crown ether pendent monomer and CD pendent monomer were synthesized for polymerization with thermo responsive NIPAM. Also, the CD-NIPAM copolymer chains were fixed in porous substrate pores, and a novel chiral separation membranes were developed. Those polymer and membranes showed host-guest recognition, and its recognition ability can be controlled by stimuli responsive polymer's volume change. This means that molecular recognition type separation can be occurred by slight temperature change as expected.
