Chiral Molecules and the Electron's Spin- From Spintronics to Enantio-Separation
![]()
Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, we found that chiral organic molecules act as spin filters for photoelectrons transmission, 1 in electron transfer, 2 and in electron transport. 3
The new effect, termed Chiral Induced Spin Selectivity (CISS), 4,5 was found, among others, in bio-molecules and in bio-systems. It has interesting implications for the production of new types of spintronics devices 6,7 and on electron transfer in biological systems. 8 Recently we found that charge polarization in chiral molecules is accompanied by spin polarization. 9 This finding shed new light on enantio-specific interactions and it opens the possibility to construct novel methods for enantio-separation.
