一种双酯液晶的合成及表征
摘要
通过1-溴辛烷与对羟基苯甲酸反应,其产物用DCC/DMAP高效酯化法与邻甲基对苯二酚合成的双-(对辛氧基苯甲酸)邻甲基对苯二酚酯,通过红外、核磁、偏光显微镜等对其结构及液晶性能进行了研究。

1SHI Yongji(Luoyang Technology College,Luoyang 471003,CHN)Abstract: A liquid crystal moving picture projector and method are described.Light incident on a liquid crystal display-type device is selectively scattered or transmitted by respective portions of liquid crystal display,and a projection mechanism projects an image formed by either such scattered light or such transmitted light.A liquid crystal moving picture projector includes a liquid crystal display for creating characteristics of an image,and projecttion optics for projecting images sequentially created by the display.The display includes a liquid crystal material capable of temporary storing information at respective areas.The temporary storage may be a function of charge storing directly on liquid crystal material.A method of projecting plural images in sequence includes:creating an image or characteristics of an image in a liquid crystal material,storing such image in such liquid crystal material,directing light at such liquid crystal material,projecting such image as a function of light transmitted through or scattered by such liquid crystal material,and creating a further image in such liquid crystal material for subsequent projection..Liquid Crystal Motion Picture Projector[J].Semiconductor Photonics and Technology,1997,3(3):198-203. 被引量:37
