Abstract: Spin selective electron transmission made chiral biomolecules a very promising candidate for pharmaceutical and chemical industries. By controlling the relative spin orientation and manipulating the spin directions, one can guide chemical transformations. We have demonstrated many experiments through the chiral induced spin selectivity (CISS) effect that; efficient electron transport through chiral molecules and materials depends on the helicity and the electron spin orientation. Here we explained the temperature dependent CISS effect by experiment and theoretical model, which includes the vibrational contribution to the spin orbit coupling.[1,2]

The angular dependent magnetic field and temperature on the CISS effect were analyzed, which provide an insight that; phonon may contribute to the spin polarization in the magnetoresistance devices. We also explain the spin-polarization induced chirogenic electro-polymerization of achiral polymer.[3] This process has formed chiral polymer from an achiral reagent without a chiral catalyst demonstrates the power of spin-induced enantiospecific chemistry.
