Abstract:

I 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.  I will discuss how 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. I 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 enhance (enantio)selectivity in electrochemical reactions.
