A4 Liquid Crystals

Figure 11.2
The molecule shown is used in liquid-crystal displays (LCDs). Identify two physical characteristics of this molecule that makes it suitable to assemble into a liquid crystal state.
2. Liquid crystals can be classified into three different types including thermotropic, lyotropic and nematic liquid crystals. i. Briefly explain the difference between thermotropic and lyotropic liquid crystals ii. Describe the shape and arrangements of molecules that form nematic liquid crystals – this can be done with the aid of a labelled diagram.
