碩士 === 國立東華大學 === 化學系 === 96 === A new interfacial enzymatic method for chiral polyaniline was developed using 1-butyl -3-methyl imidazolium hexafluorophosphate (BMIM-PF6) water immiscible ionic liquid(IL) to aqueous/ionic liquid interface and to protect the enzymes under acidic reaction conditions. The better chirality of polyaniline was obtained in lower temperature, such as the 4 oC . The optimal conditions were as follow: 0.0016mole aniline monomer mixed with 1 mL 2M camphorsulfonic acid as aqueous layer and 6mg peroxidase dissolve in 1mL BMIM PF6 as IL layer and then incubated 36 hours statically at 4oC. The different optical spectrums were found under the same optical activity camphorsulfonic acid as dopant. It shows that the peroxidase is the main factor to induce the optical activity. IL could be reused repeatly for at least 5 times . however, the chirality of polyaniline will decrease comparing with the first time using of IL.
