摘      要：Chirality,one of the most fundamental characteristics of nature,plays an important role in different fields ranging from physics to astronomy,chemistry and biology[1].Materials with certain chirality usually show unique optical and photophysical properties.The chiral-induced spin selectivity(CISS)effect,which was first reported in 1999,is considered as one of the most important spin-related properties of chiral materials.The electron transportation through chiral materials depends on the electron spin.That is,the electrons with a certain spin state such as spin-up state can pass through the chiral materials more easily in one direction,while the transportation of electrons in the spin-down state will be blocked.Therefore,the distinct advantage of CISS effect opens up the possibility to control and manipulate the spin orientation of electrons without using external magnetic fields,which is promising for the fabrication of new spintronic devices[2].
