摘要

Difluorooxymethylene-bridged(CF2O)liquid crystal(LC)with low viscosity is prepared and used as a fast response LC material.When the material is mixed with isothiocyanato LCs with high birefringence,the visco-elastic coefficient of the mixture decreases evidently and,accordingly,the response performance increases.While the concentration of CF2O LCs is about 7%,the LC mixture approximately maintains high birefringence and exhibits a fastest response performance that is 14%higher than that of pure isothiocyanato LCs.Therefore,the LC material and mixing method could find useful applications in optical devices.
