Professor Waldeck will describe recent studies that investigate the effects of electron spin in electron transfer and electron initiated chemical reactions of supramolecular assemblies and at electrodes. Charge polarization and charge transfer in chiral molecules and assemblies is accompanied by spin polarization and spin transfer, because of the chiral induced spin selectivity (CISS) effect. In the first part of the talk, he will describe the discovery of CISS 1999 and trace our understanding of its basic features through an exposition of key experiments. In the second part of the talk, he will report on recent studies which show how the CISS effect modulates electron transfer rates in chiral assemblies and how spin-filtered electron transfer can be used to initiate enantioselective electrochemical reactions.
