项目摘要

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.

在这项研究中，研究了基于苝四甲酰亚胺（PTCBI）核的液晶半导体。合成了带有四个烯基的 PTCBI 衍生物，并使用 Karstedt 催化剂在侧链末端引入了低聚硅氧烷链。这些化合物在室温下呈现柱状相，即使冷却至-100 oC 也不会结晶。它们在室温下在柱状相中表现出高电子迁移率，并且在化合物的有序柱状相中电子迁移率超过0.1 cm2/Vs。这些化合物可溶于除醇以外的各种有机溶剂。可以通过旋涂方法在玻璃基板上生产薄膜。使用摩擦转移方法，可以生产单轴取向的薄膜。已经合成了带有可聚合环四硅氧烷部分的LC PTCBI衍生物。环四硅氧烷部分通过亚己基与核连接的化合物在室温下表现出无序柱状相，通过飞行时间法测定室温下的电子迁移率为2x10-4cm2/Vs。该化合物还溶于多种有机溶剂，可通过旋涂法制备薄膜。该化合物在三氟甲磺酸存在下聚合。目前正在研究聚合条件。
