A mesogen is a compound that displays liquid crystal properties. [1] [2] Mesogens can be described as disordered solids or ordered liquids because they arise from a unique state of matter that exhibits both solid- and liquid-like properties called the liquid crystalline state. [1]

液晶原（mesogen）是液晶的功能单位，液晶分子由刚性部分和柔性部分组成。 刚性部分使分子在一个方向上排列，而柔性部分诱导在液晶中的流动性。 该刚性部分被称为液晶原（mesogen）。 高分子液晶 按其液晶原所处位置不同而分为主链型和侧链型液晶。 主链液晶的主链即由液晶原和柔性链节相间组成。 侧链液晶的主链为柔性，刚性的液晶原接在侧链上。 液晶原（mesogen）是液晶的功能单位，液晶分子由刚性部分和柔性部分组成。

A mesogen is rigid rodlike or disclike molecules which are components of liquid crystalline materials. It is sometimes difficult to determine whether a material is in a crystal or liquid crystal state.

2023年12月1日 · Mesogen jacketed liquid crystalline polyacetylene containing triphenylene discogen: synthesis and phase structure

2021年6月30日 · Mesogenic units, also called reactive mesogens, incorporated into the polymeric backbones as side chains of weakly cross-linked macromolecules, can form orientationally ordered nanostructures.

2022年1月21日 · Here, we develop a fast synthesis route to produce a new type of reactive mesogen based on an aromatic–imine structure that intrinsically enables a fast and stable bond-exchange reaction in the resulting imine-based xLCE. This new xLCE displays vitrimer plastic-flow behavior, and its bond-exchange activation energy is calculated to be 54 kJ/mol.

In a discotic liquid crystal, the flat-shaped aromatic core that makes molecules stack in one direction is defined as the mesogen. These rod-like and disk-like structures are formed not only by covalent bonds, but also by non-covalent interactions, such as hydrogen bonds, ionic interactions, and metal coordination.
