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, in electron transfer, in electron transport. The effect, termed Chiral Induced Spin Selectivity (CISS), [1,2] lead to the discovery that when chiral molecules are charge polarized, there is a transient spin polarization [3]. At each electrical pole, the (partially) unpaired electron is spin polarized with opposite polarization at the positive and negative poles. Which spin is associate with which pole depends on the handedness of the molecule. This finding sheds new light on enantio-specific interactions and it allows to construct novel methods for enantio-separation.[4,5] It also opens new ways to induce spin polarization enantio-selective chemistry.<br/><br/><br/><br/>
