  • Bioreachable chiral dopants for liquid crystal applications
    Patent number: 11814563
    Abstract: 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-naringenin (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.
    Type: Grant
