Dielectric studies of a chiral fluorinated organosiloxane liquid crystal

Research output: Contribution to journalArticle

Abstract

The material (LC#11) we are reporting in this communication is a chiral fluorinated organosiloxane liquid crystal which has a long chain hydrocarbon head and ending with a straight trisiloxane terminus. Polarized optical microscopic studies revealed that the material exhibits SC, SA phases along with a co-existent biphasic region. The material responds to electric field; at low temperature the response is slow. Tilt angle measurements as a function of temperature are carried out using optical extinction method. Low frequency dielectric studies are carried out using Wayne Kerr precision impedance analyzer.
