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-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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit to U.S. Provisional Application No. 62 / 776,957, filed December 7, 2018, which is incorporated herein by reference in its entirety. [0003] Statement Concerning Rights to Inventions Made Under Federally Sponsored Research and Development [0004] This invention was made with Government support under Agreement No. HR0011-15-9-0014 awarded by DARPA. The government has certain rights in this invention. technical field [0005] The present invention relates generally to the field of optically active dopants, and more particularly to chiral dopants derived from biological resources. Background technique [0006] Electromagnetic (EM) radiation is everywhere, including X-rays through ultraviolet, visible light, infrared, radio frequency and low frequency waves. Protecting people and equipment from harmful radiation is an essential task. At optical frequencies, optical filters a...
