Abstract A disubstituted polyacetylene with lyotropic liquid crystallinity showing SmA was synthesized. The number-average-molecular weight of the polymer was 5.2 × 105 g/mol. Vapor phase iodine doping for the disubstituted polyacetylene in the form of liquid crystal order allows the generation of charge carriers. The ESR measurements show the charge carriers exhibit Pauli paramagnetism, indicating that these carriers are polarons. Mott-type variable range hopping (VRH) conduction of the polymer was observed. The combination of SmA molecular architecture and electrical conduction by polyene as a molecular wire in the polyacetylene derivative results in liquid crystal electrical conduction via electro-soliton movement.

液晶聚乙炔中的孤子激发

摘要 合成了一种显示SmA 的溶致液晶性双取代聚乙炔。聚合物的数均分子量为 5.2 × 105 g/mol。以液晶有序形式对二取代聚乙炔进行气相碘掺杂允许产生电荷载流子。ESR 测量显示电荷载流子表现出泡利顺磁性，表明这些载流子是极化子。观察到聚合物的莫特型可变范围跳跃 (VRH) 传导。SmA分子结构与聚乙炔衍生物中多烯作为分子线的导电性的结合导致液晶通过电孤子运动进行导电。
