Chiral is optically active
Webuniversal form of a chiral object and thus far has been the most studied optically active structure. Artificial chiral materials were studied by Bose almost a century ago [4], and he demonstrated rotation of the plane of polarization of electromagnetic waves as they traversed a jute bundle. WebApr 7, 2024 · A chiral dopant ((R)-BB, 0.05 or 0.25 wt%) was also added, in order to induce with a pitch of 44.7 or 8.9 µm. Once introduced into a 20 µm thick electro-optical cell, the chiral nematic helices experience a confinement ratio of ≈0.5 and ≈2.2, which leads to the formation of HH and SFLH patterns, respectively, once low voltage is applied.
