4-Pentylphenyl 4-methoxybenzoate (PPMB), CAS number 38444-13-2, also known as Nematal 105, is a nematic liquid crystal slightly above room temperature with a chemical structure of 4-methoxyphenyl ester of 4-pentylphenyl.
4-Pentylphenyl 4-methoxybenzoate can act as a host material for luminophores such as N,N′-Bis(2,6-dimethylphenyl)perylene-3,4,9,10-tetracarboxylic diimide (PDI). When PDI is dissolved in the liquid crystal host to an approximate concentration of 10-5 M. PDI molecules are successfully aligned within a nematic liquid crystal. The homeotropic alignment leads to decreased surface losses, despite increased absorption when illuminated through the narrow edges. 4-Pentylphenyl 4-methoxybenzoate can also be used as a achiral host of chiral compounds which induce a helical ordering and thus create a chiral nematic phase, the so called chiral nematic liquid crystal with helical structures.
