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.
