폴리(3-티오펜아세틱에시드)와 계면활성제 복합체의 합성과 물성 연구

Abstract

Polythiophene derivatives are important representative class of conjugated polymers that form some of the most environmentally and thermally stable materials that can be used as optical devices. We synthesized poly(3-thiopheneacetic acid) (P3TAA) and P3TAAsurfactant complexes. All the complexes with amphiphile counterions displayed ordered mesophases. These results show that fully developed layer structures were constructed by self-assembled behavior via ion interaction. They are side-chain crystalline, smectic A, and smectic B-like phases in the solid state at room temperature. The red shifts of UV-vis absorption spectra as increase alkane side chain length were observed. Photoluminescence spectra were shown same tendency. Polymer and all complexes were investigated by using IR, NMR, POM, DSC, UV-vis, PL, WAXS, and SAXS.
