Artykuł
The electric-field-induced reorientation of the C*phase of 5-(2-fluorooctyloxy)-2-(4-octylphenyl)-pyrimidine was investigated by using an asynchronous time-resolved FT-IR technique. The time-resolved study indicates that the liquid crystal (LC) molecule reorients from perpendicular (zero time of delay) to parallel (500μus delay) direction with respect to that of the polarized infrared light at 32°C while it does reversely at 41°C. It is also shown that the change in the voltage applied has little influence on the rate of reorientation in the region of the positive spontaneous polarization (Ps), while the rate in the region of the negative Ps strongly depends upon the voltage.
