General description

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

Application

Monolayer films of the LCs deposited onto highly ordered pyrolytic graphite, these self-assembled films display a wide variety of structural forms.
8CB may be used in the preparation of asymmetrical zinc phthalocyanine (aZnPc)-functional photocurable copolymer.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
