Examples of molecules which form liquid crystals
4-methoxylbenzylidene-4'-butylaniline (MBBA) transforms from crystalline to nematic liquid crystal at 20ºC, and from nematic to an isotropic liquid at 74ºC
This very similar molecule forms a chiral nematic (cholesteric) liquid crystal. The chiral centre is marked with a *.
4-cyanobenzylidene-4'-n-octyloxyanaline (CBOOA) forms a smectic liquid crystal below 83ºC and a nematic liquid crystal between 83ºC and 109ºC.
