Cholesteric liquid crystals are frequently produced by the addition of chiral dopants to achiral nematic hosts. We report here the synthesis and performance of chiral dopants obtained from bio-betulin produced by a fermentation process. An important aspect of this work is to point out that the fermentation process used to obtain the starting materials is much easier and cheaper when carried out in large volumes than isolating it from the natural product. The performance of the dopants obtained from bio-betulin is indistinguishable from those obtained from commercially available synthetic betulin.

Three kinds of novel planar chiral azobenzenophane with high HTP values were synthesized. Then, cholesteric liquid crystals with different screw directions were induced by them successfully. And reversible tuning between orange and green reflection colors was achieved.

9,9′-biphenanthrene-type chiral dopants were newly synthesized for the development of functional liquid crystal (LC) materials with enhanced properties. A cholesteric LC (CLC) with a chiral dopant showed positive temperature dependence of helical twisting power and a CLC with temperature independence was developed by mixing two types of chiral dopants.
