Liquid crystal (LC) building blocks are molecules that can form liquid crystals, substances that exhibit properties between liquids and crystals. These building blocks have a unique molecular structure that enables them to self-assemble into ordered structures with anisotropic properties. Liquid crystals are used in a variety of applications such as displays (LCDs), sensors, and photonic devices. In displays, they can control the transmission of light to create images. In sensors, they can detect changes in physical properties such as temperature and pressure. In photonic devices, they can manipulate light to create new optical functions.
