四氟苯系列液晶中间体的应用与发展

Application and Development of Tetrafluorobenzene Series Liquid Crystal intermediates

随着信息和电子等行业的快速发展,全球LCD产业已经走上了高速发展的轨道。氟化液晶化合物是关键中间体之一,由该原料合成的含氟液晶具有低黏度,中等折射率和宽的液晶相温度范围,并且具有优异的整体性能。目前,含氟液晶中间体,特别是TFT-LCD(薄膜晶体管液晶显示器),近来已成为发展的热点。主要介绍了四氟苯系列液晶中间体的开发和应用。

With the rapid development of information and electronics industries,the global LCD industry has embarked on a highspeed development track.The fluorinated liquid crystal compound is one of the key intermediates,and the fluorine-containing liquid crystal synthesized from the raw material has a low viscosity,a medium refractive index,and a wide liquid crystal phase temperature range,and has excellent overall properties.At present,fluorine-containing liquid crystal intermediates,especially TFT-LCD(thin film transistor liquid crystal displays),have recently become a hot spot of development.This paper mainly introduces the development and application of tetrafluorobenzene series liquid crystal intermediates.
