Cyclohexanecarboxylic acids are cyclic fatty acids that can be incorporated into liquid crystal molecules to improve their flexibility and processability. The presence of the cyclohexane ring provides a stable platform for the attachment of various functional groups, allowing the customization of LC properties. These acids are used as precursors for the synthesis of LC building blocks with specific mesomorphic phases. Liquid crystals based on cyclohexanecarboxylic acids are used in a variety of applications, including temperature sensors, optical filters, and advanced display technologies, where their unique combination of properties is advantageous.
