Mechanical Rotational Model of Phase Transition in Clubbed Liquid Crystal Molecules

Relationship between molecular structure and clubbed liquid crystal phase is summarized. A mechanical rotational model for liquid crystal molecules is introduced. In the model,liquid crystal molecule is regarded as a rotor rotating rapidly. By calculating some molecular parameters,a novel explanation on relationship between phase transition temperature and liquid crystal molecular structure is obtained. In recent study,a phenomenon which is called slim and fat isomers is found in fluorinated terphenyl liquid crystal compounds. And it can give a reasonable explanation on the liquid crystal phase transition. The model can furnish some useful message on designing and synthesizing of liquid crystal molecule by a simple way.
