Field-induced molecular re-orientation dynamics of a surface stabilized ferroelectric liquid crystal

Abstract

In this study, combination of linear optical properties measurement with polarized time resolved infrared spectroscopy, the information of molecular switching dynamicsfrom the macroscopic optical axis orientation and the detail switching behaviors in molecular scale is revealed. We found that the SSFLC molecules can be considered as a rigid system when extemal electricfield is on, but when thefield is removed, the transient behaviors of dferent molecules segments are not completely coherent, and the collected model cannot applied directly in the relaxation period.
