WebOptically active polymers are certainly essential in a variety of potentials, including materials science, chemical and biological sensing, enantioselective separations, asymmetric catalysis, and chiral stationary phases. Synthetic chiral polymers can be produced by several strategies like asymmetric synthesis. WebApr 22, 2024 · Chiral electromagnetism, often referred to as optical activity (OA), has two main properties that describe the way a wave interacts with a given chiral medium. The first is optical rotatory dispersion (ORD) in which the polarization of a wave is rotated as it passes through a chiral medium.
