Syntheses and electrical properties of poly(2-acetoxy-1,4-phenylenevinylene) and poly(2-mesyloxy-1,4-phenylenevinylene)폴리(2-아세톡시-1,4-페닐렌비닐렌)과 폴리(2-메실옥시-1,4-페닐렌비닐렌)의 합성 및 전기적특성에 관한 연구
New asymmetrically substituted poly(2-acetoxy-1,4-phenylenevinylene), PAPV and poly(2-mesyloxy-1,4-phenylenevinylene), PMSPV were prepared via water soluble precursor polymer route. They were characterized by DSC, TGA, UV/VIS and FT-IR. They were readily doped with $FeCl_3$ at room temperature. Precursor film of PMSPV could be readily stretched before or during the elimination, but that of PAPV could not be stretched. Conductivity of unstretched PAPV and PMSPV were 19.4S/cm and 0.26S/cm respectively. But uniaxially drawn film(draw ratio=6) of PMSPV gave a conductivity of 20.4S/cm along the draw direction. This conductivity value was increased 78times than that of unstretched PMSPV. From FT-IR investigations, the precursor film of PAPV was thought to be converted into poly(2-hydroxy-1,4-phenylenevinylene) by the elimination of acetxy group at some extent. But the precursor film of PMSPV did not change during the elimination.
