In this study, liquid crystalline semiconductors based on perylene tetracarboxylic bisimide (PTCBI) cores have been studied. PTCBI derivatives bearing four alkenyl groups were synthesized and oligosiloxane chains were introduced at the terminals of the side chains using Karstedt catalyst. These compounds exhibit columnar phases at room temperature and do not crystallize even when they are cooled to -100 oC. They exhibit high electron mobilities in the columnar phases at room temperature and the electron mobility exceeds 0.1 cm2/Vs in ordered columnar phase of a compound. These compounds are soluble in various organic solvents except for alcohols. Thin films can be produced on glass substrates by a spin-coating method. Using friction transfer method, uniaxyally aligned thin films can be produced. LC PTCBI derivatives bearing polymerizable cyclotetrasiloxane moieties have been synthesized. The compound in which the cyclotetrasiloxane moieties are connected to the core via hexylene groups exhibits a disordered columnar phase at room temperature and the electron mobility is determined to be 2x10-4cm2/Vs at room temperature by the time -of-flight method. The compound is also soluble in various organic solvents and thin film can be produced by the spin-coating method. The compound polymerizes in the presence of trifluoromethane sulfonic acid. Now the polymerization condition is being investigated.

在本研究中，我们研究了以四甲基茂铁联亚胺(PTCBI)为核心的液晶半导体。用Karstedt催化剂合成了含四个烯基的PTCBI衍生物，并在侧链末端引入了低聚硅氧烷链。这些化合物在室温下呈柱状相，即使冷却到-100℃也不结晶。在室温下，它们在柱状相中表现出较高的电子迁移率，在化合物有序柱状相中的电子迁移率超过0.1cm2/vs。这些化合物可溶于除醇以外的各种有机溶剂。用旋涂的方法可以在玻璃衬底上制备薄膜。采用摩擦转移法可以制备出单轴取向的薄膜。合成了含可聚合环四硅氧烷的LC-PTCBI衍生物。环四硅氧烷基团通过己烯连接到核上的化合物在室温下呈现无序的柱状相，用飞行时间法测得室温下的电子迁移率为2×10~(-4)cm~2/vs。该化合物还可溶于各种有机溶剂，可通过旋涂法制备薄膜。该化合物在三氟甲烷磺酸存在下聚合。目前，聚合条件正在研究中。
