Response speed of liquid crystal displays(LCD) is contrast to the rotational viscosity of liquid crystal materials. So far

the problem that low-temperature magnitude dependence of viscosity and response time was not been resolved

which has become the bottleneck of development and application of liquid crystal display technology. In this paper

the difluoromethoxymthylene-bridged alkylbenzenes compounds with two aromatic rings were used as liquid crystal components and solvents

to study their behavior of viscosity at different temperature. It was found that compositions not only were super low viscosity and very small temperature dependence

but also can be used as liquid crystal solvent and components to reduce the viscosity and the low-temperature dependence of liquid crystal materials effectively.
