Abstract
Latest progress in the liquid crystal (LC) field related to azo molecules incorporated into natural product-
based moieties for the improvement of LC texture and mesomeric phases has received great interest among
researchers. A LC containing natural product-based moieties i.e. menthol, kojic acid, cholesterol and chalcone
with stable azo and azobenzene scaffolds with specific optical tunability, has been widely used in photo-active
materials such as Liquid Crystal Display (LCD), LC films, smart windows and other devices. This review discusses
the influence of azobenzene, a renowned photo-responsive and stable LC scaffold, in mesogenic phases
due to photo-isomerization and optical switching. The incorporation of mesomeric phases of natural product
moieties to azo molecules has improved the properties of LC, i.e, from the nematic phase to the smectic phase
with proper magnetic field alignment. Natural product-based LC can be useful in numerous applications, especially
practical electronic or optic devices such as optical image storage, display devices, solar cells, optical
switching.
