Mesogen

  "id": "MLC-T-CHM-007212",
  "term": "Mesogen",
  "field": "Chemistry",
  "definition": "A compound whose molecules, given the right temperature, pressure or concentration, organise into a mesophase, in particular a liquid-crystal phase. Most mesogens have a rigid, rod-like or disc-like core, and its shape decides whether nematic, smectic or columnar phases form. The rigid part of a molecule that drives this behaviour is called the mesogenic group.",
