The synthesis of two kinds of intermediate for material about acetylferrocene at one reaction but different factors were studied for the first time,and the structures of the compounds have been characterized by elemental analysis, infrared (IR) and nuclearmagnetic spectroscopy (~1HNMR).

This paper presents an improved process for the preparation of the novel liquid crystal 5-propyl2-(3,5-difluorophenyl)pyrimidine.

By using Nd∶YAG mode locked pulse laser (λ=532 nm, τ 0=35 ps), the third order nonlinear optical susceptibility χ (3) , and time response properties of liquid crystals containing Schiff base and Naphthalimide are measured with forward degenerate four wave mixing (DFWM).

A new method for the determination of cations on the organic molecule in the liquid crystal materials by ultraviolet(UV) photolysis ion chromatography was developed.

Progress of liquid crystal materials for VA-TFT;

The developing of photorefractive liquid crystal material;

Relationships of LCD TV among response time,operating voltage and liquid crystal materials parameters are introduced under three modes including vertical alignment(VA)mode,in plane switching(IPS)mode and twisted nematic(TN)mode.

Orientated polycrystal, quasi-single crystal or single-crystal materials can be easily distinguished, and the crystal quality of quasi-single and orientated crystal materials in proc.
