4′-(2-(2-Ethoxyethoxy)ethoxy)biphenyl-4-carboxylic acid-a polar smectogen for amphipathic liquid crystals

We describe a new calamitic smectogen and some of its esters with a three-block molecular architecture (polar oxyethylene chain, rigid biphenyl and non-polar aliphatic chain) which were characterised by a combination of optical, thermical, X-ray and computational techniques. The title compound is a valuable smectogenic building block for amphipathic functional organic materials.
