Beschreibung

Allgemeine Beschreibung

4′-Pentyl-4-biphenylcarbonitrile (5CB) is a nematic liquid crystal. 5CB undergoes phase transition from crystalline to nematic then to isotropic state at 18^oC and 35^oC respectively. It may be produced by modifying biphenyl.2

Anwendung

Attaching 5CB to an aqueous-liquid crystal interface by redox active surfactant has been investigated.
