一个合理的，面向积木的设计方法产生了一类新的“超氟化”液晶适用于最新一代的有源矩阵液晶显示器。这些材料在其介晶核结构中含有不同氟化连接基团的组合，从而产生非常有利的性质分布，包括宽的介电相范围、低旋转粘度和高介电各向异性。这种复杂材料的大规模合成仅通过α，α-二氟醚键的合成的一些最新进展才变得可行。(C)2001爱思唯尔科技有限公司。保留所有权利。
A rational, building block oriented design approach gives rise to a new class of "super fluorinated" liquid crystals suitable for the newest generation of active matrix LCDs. These materials contain combinations of different fluorinated linking groups in their mesogenic core structure, resulting in a highly advantageous property profile including a broad nematic phase range, low rotational viscosity and high dielectric anisotropy. The large-scale synthesis of such complex materials became feasible only by some recent advances in the synthesis of alpha,alpha -difluoroether linkages. (C) 2001 Elsevier Science B.V.
