Chirality and the Electrons’ Spin- How Nature Utilizes the Relation between Them and How We Can Do It

Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. However, we found that chiral organic molecules can act as spin filters for photoelectrons transmission,[i] in electron transfer,[ii] and in electron transport.[iii]

The new effect, termed Chiral Induced Spin Selectivity (CISS),[iv] has interesting implications in Biology,[v] varying from allowing long-range electron transfer, controlling multiple electrons reactions, and in enantio-recognition. It also opens the possibility to apply chiral molecules in spintronics.[vi]

The effect and its various applications and implications will be discussed.
