Mesogen

Mesogens are a type of molecule that play a crucial role in the field of liquid crystals. Specifically, they are the mesogenic units that possess elongated shapes and are responsible for the liquid crystalline properties of materials. These molecules can orient themselves in a way that allows them to exhibit both liquid and solid characteristics, depending on temperature and other conditions. Generally, mesogens contain a rigid core, often composed of aromatic rings, along with flexible alkyl chains.
