Description

General description

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

Application

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

Transition from Spin Dewetting to continuous film in spin coating of Liquid Crystal 5CB.

Palash Dhara et al.

Scientific reports, 8(1), 7169-7169 (2018-05-10)

Spin dewetting refers to spontaneous rupture of the dispensed solution layer during spin coating, resulting in isolated but periodic, regular sized domains of the solute and is pre-dominant when the solute concentration (C n ) is very low. In this

Coupling of the orientations of thermotropic liquid crystals to protein binding events at lipid-decorated interfaces.

Jeffrey M Brake et al.

Langmuir : the ACS journal of surfaces and colloids, 23(16), 8497-8507 (2007-06-28)

We report a study of the interactions of proteins with monolayers of phospholipids (D/L-alpha-dipalmitoyl phosphatidylcholine and L-alpha-dilauroyl phosphatidylcholine) spontaneously assembled at an interface between an aqueous phase and a 20-microm-thick film of a nematic liquid crystal (4'-pentyl-4-cyanobiphenyl). Because the orientation

Preparation of microscopic and planar oil-water interfaces that are decorated with prescribed densities of insoluble amphiphiles.

Maria-Victoria Meli et al.

Journal of the American Chemical Society, 130(13), 4326-4333 (2008-03-14)

Langmuir monolayers (monolayers of insoluble molecules formed at the surface of water), and associated Langmuir-Blodgett/Schaefer monolayers prepared by transfer of Langmuir films to the surfaces of solids, are widely used in studies aimed at understanding the physicochemical properties of biological
