網頁2024年4月2日 · Abstract Synthetic chiral platforms can be a powerful platform for enantioselective interactions, especially when coupled with redox-mediated electrochemical processes. While metallopolymers are ve... For the synthesis of N-(1-ferrocenylethyl) methacrylamide ((S)− and (R)−1), the racemic 1-ferrocenyl-ethylamine was prepared by … 網頁formalism [18,19]. The chiral separation can also be induced by an electric field, which is called the chiral electric separation effect (CESE) [20–23]. If the electric field is perpendicular to the magnetic field, a Hall current for chiral fermions is expected, which is
