General Description
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.
