Pharmaceutical Chemistry (Inorganic)

Liquid crystals, the fourth state of matter, exhibit an intermediate order between liquids and crystals. Divided into thermotropic and lyotropic classes, they include high molar mass polymers and low molar mass materials like discotic and rod-like molecules. Rod-like liquid crystals, such as nematic and chiral nemetic, display unique orientational patterns. Applications in pharmacy range from super-strength polymers for drug delivery to liquid crystal thermography for evaluating medical conditions.
