We report a mesogenic compound which introduces nematic liquid crystal (LC) ordering into the benzothienobenzothiophene (BTBT) family of LCs, creating a new class of LC semiconducting materials which respond in a facile way to anisotropic surfaces, and can, thereby, be effectively processed into highly oriented monodomains. Measurement on these domains of the electrical conductivity, with in situ monitoring of domain quality and orientation using LC birefringence textures in electroded cells, brings a new era of precision and reliability to the determination of anisotropic carrier mobility in LC semiconductors.

用于有机场效应晶体管的高度取向液晶半导体

我们报道了一种介晶化合物，该化合物将向列液晶（LC）引入到LC的苯并噻吩并苯并噻吩（BTBT）系列中，从而创建了一种新型的LC半导体材料，该材料能够以一种简便的方式对各向异性表面做出反应，从而可以有效地对其进行处理。进入高度定向的单域。通过使用电化电池中的LC双折射纹理对电导率的这些域进行测量，并使用LC双折射纹理对域质量和取向进行现场监测，为确定LC半导体中各向异性载流子迁移率带来了精确和可靠的新时代。
