中文摘要：
大共轭π-电子体系的多环芳烃盘状液晶具有较好的自组装有序性和优良的光、电、磁物理特性，是一类新型有机半导体材料，在高技术领域有较大应用前景。本项目通过分子设计，合成了含乙炔基和苯乙炔基通过间隔基或直接连接的苯并菲盘状液晶单体。并在分子设计上采用含手性柔链(R*)，可形成氢键的官能团(-CONH-)的盘状单体分子以及全氟链的棒状和盘状液晶化合物。通过对Rh, Mo, W等乙炔聚合反应催化剂体系的筛选与反应条件优化，首次合成了盘状聚乙炔高分子液晶。通过XRD, TGA, DSC, POM等测试，显示聚合物具有较好的热稳定性和液晶性。通过分子刚性实结构的改变，分子间相互作用强度的调节，获得了高的电荷传输速率的盘状液晶半导体。通过调节乙炔基、苯乙炔基与盘状介晶基元间间隔基长度，侧链介晶基元间相互作用强弱（盘状芳核间氢键、间隔基间氢键等），探索了分子结构、聚合反应条件与收率、聚合物分子量、分子量分布间关系及其的规律。本项目在液晶合成及聚合新催化体系开发，盘状液晶分子超分子自组装规律，以及新的盘状液晶半导体化合物的合成与性能研究等领域取得了有较高学术意义和实用价值的研究成果。
