The Chiral-Induced Spin Selectivity Effect

Our group is examining the nature of the Chiral-Induced Spin Selectivity (CISS) effect and exploring ways in which it can be exploited technologically. As electrons move through a chiral molecule (or structure) the electron current generates an effective magnetic field, B, that acts on the electrons’ intrinsic magnetic moment. Thus, a preference exists for electrons with one magnetic moment direction to pass through the chiral molecule (or structure).

CISS dates from 1999 (K.Ray et al. Science 283, 814), in which Waldeck  and Naaman reported that the transmission yield of spin-polarized electrons through chiral Langmuir-Blodgett films depends on the handedness of the molecular films. Since that time, CISS has been shown to be manifest in electron tunneling processes, electron transfer reactions, and in ferrogmagnetic surface/molecule exchange interactions. A number of different reviews on CISS itself (R1, R2) and its implications in Biology, Chemistry, and Physics are available (R3-5). Our group is exploring fundamental aspects of of CISS in an effort to provide quantitative data that is useful for guiding theoretical descriptions, and we are exploring how CISS may prove useful for improving enantiospecificity in chemical technologies and spin-selectivity in opto-electronic phenomena.
