Zusammenfassung: | The action of chiral modifiers like cinchonine and cinchonidine in facilitating enationselectivity in heterogeneous catalysis is investigated using a combination of electrochemical and scanning probe methods. The surface chirality of corner kink sites is suggested as being crucial for chirality recognition at supported catalyst nanoparticles. Other aspects of chirality in relation to one, two, three and four dimensions are also discussed.
Mass production of chiral materials lies at the heart of new developments in surface catalysis and electrocatalysis. The action of surface‐adsorbed chiral modifiers, such as the alkaloids cinchonine and cinchonidine, in facilitating enantioselectivity in heterogeneous catalysis (see graphic) is investigated using a combination of electrochemical and scanning probe methods. The surface chirality of corner kink sites is suggested as being crucial for chirality recognition at supported catalyst nanoparticles. |
