4-Pentylphenyl 4-pentylbenzoate, liquid crystal (nematic)
Liquid crystal for the application of optical electronics i.e. in liquid-crystal display (LCD).
4-Pentylphenyl 4-pentylbenzoate (5PEP5) is a nematic liquid crystal with a chemical structure of 4-pentylphenyl ester of 4-pentylbenzoate.
4-Pentylphenyl 4-pentylbenzoate has a ester link and a core which is more flexible and less directed along the long molecular axis that the biphenyl liquid crystals, i.e. 4'-Heptyl-[1,1'-biphenyl]-4-carbonitrile. However, the observed alignment properties of 4-pentylphenyl 4-pentylbenzoate having two pentyl tails on its self are similar to those of the rode-like biphenyl core molecule 4-pentyl-4’-cyanobiphenyl. The alignment on the substrate polyvinyl imidazole (PVI) is perpendicular to the rubbing direction, perpendicular to the vinyl backbone
