Abstract

Banana-shaped liquid crystal called F-490 composed of achiral molecules has been examined by means of polarizing microscopy, differential scanning calorimetry (DSC) as well as optical (visible and UV) and dielectric spectroscopy methods. The results show phase diagram of this compound. It forms monotropic liquid crystal phase called B 2 which is antiferroelectric. Moreover the formation of solid phase depends upon thermal history.
