Descripción

Descripción general

4′-octyl-4-biphenylcarbonitrile (8CB) is a low molar mass liquid crystal (LC), which shows different liquid crystalline phases depending on temperature conditions. Under normal temperature conditions 8CB exists only as a bulk smectic-A phase. LCs are responsive to subtle changes in temperature, shear, electric (or magnetic) fields, and the structure of solid surfaces with which they are in contact.

Aplicación

Monolayer films of the LCs deposited onto highly ordered pyrolytic graphite, these self-assembled films display a wide variety of structural forms.
