The disclosure discusses chiral dopants for liquid-crystalline materials. Chiral dopants can be bioreachable compounds, i.e. compounds produced from microbes through fermentation. Chiral dopants can also include bioreachable materials that are further modified by chemical synthetic steps. Chiral dopants as discussed herein can include biomolecules such as glycyrrhetinic acid (1), S-narigenin (2), shikimic acid (3), alpha-phellandrene (4), betulin (5), malic acid (6), valencene (7), or nootkatone (8), and any stereoisomers or chemically modified derivatives thereof. The disclosure further shows optical properties of such compounds in a liquid-crystalline material.
A chiral dopant selected from the group of following structures:
The chiral dopant according to any one of the preceding claims, wherein R1, R2, R3, R4, and R5 is selected independently for each occasion from hydrogen, a methyl, an ethyl, a propyl, a butyl, a pentyl, a hexyl, a heptyl, an octyl, a nonyl, a decyl, a phenyl, a benzyl, a p-tolyl, a p-halophenyl, a p-biphenyl, a p-(4-halophenyl)phenylene, a p-(4-cyanophenyl)phenylene, an o-biphenyl, a 3,5-dimethoxyphenyl, an acetyl, a propionyl, a butanoyl, a pentanoyl, a hexanoyl, a heptanoyl, an octanoyl, a nonanoyl, a decanoyl, an undecanoyl, a dodecanoyl, a 1-naphthyl, or a 2-naphthyl.
