Cyclohexanones are ketones with a six-membered ring structure that can be modified to produce liquid crystal compounds with different properties. They provide a balance of rigidity and flexibility, which is essential for the formation of stable LC phases. The ketone functional group allows further chemical modifications, enabling the preparation of functional LC materials with tailored optical and electrical properties. Cyclohexanones are widely used in the synthesis of liquid crystal building blocks for displays, photonic devices and other optoelectronic technologies. Their ability to form ordered LC phases with specific properties makes them valuable ingredients in these advanced materials.
