WebThe use of a chiral additive such as l-cysteine or d-cysteine has been used to manipulate the handedness of the resulting nanoparticles (Fig. 1a-i, ii). 30 Because of the chiral geometry, the distributions of the electric field and magnetic field differ distinctly depending on the handedness of the incident circularly polarized light (Fig. 1a-iii). WebChiral and coordinating ionic liquids based on prolinate, valinate, and aspartate anions are used to induce CPL from a simple achiral europium triflate salt. The sign of the induced CPL is dependent on the handedness (l vs d) of the amino acid anion.
