“…For this aim, we show, both analytically and numerically, that the fact that the CISS polarization can exceed the spinpolarization of the FM electrode (as observed in numerous experiments 7,8,49,50 ), actually rules out the possibility of the CISS effect originating from a pure SOC effect without interactions. This is because in the absence of some form of interactions, the FM spin polarization is an upper bound for the CISS polarization.…”

“…In a recent tour-de-force study, Guo and co-workers used single molecule junctions and their CISS response to monitor chiral symmetry breaking in real time for a chemical reaction. 209 Here, Ni/Al 2 O 3 /graphene/single molecule/graphene/Cr/Au molecular junctions were used to monitor the spin-filtered steady-state electron currents. They measured the spin-dependent electron current through the molecular junction while it was exposed to reaction conditions for the addition of a 1,3-dicarbonyl to the maleimide functionality.…”

Since the initial landmark study on the chiral induced spin selectivity (CISS) effect in 1999, considerable experimental and theoretical efforts have been made to understand the physical underpinnings and mechanistic features of this interesting phenomenon. As first formulated, the CISS effect refers to the innate ability of chiral materials to act as spin filters for electron transport; however, more recent experiments demonstrate that displacement currents arising from charge polarization of chiral molecules lead to spin polarization without the need for net charge flow. With its identification of a fundamental connection between chiral symmetry and electron spin in molecules and materials, CISS promises profound and ubiquitous implications for existing technologies and new approaches to answering age old questions, such as the homochiral nature of life. This review begins with a discussion of the different methods for measuring CISS and then provides a comprehensive overview of molecules and materials known to exhibit CISS-based phenomena before proceeding to identify structure−property relations and to delineate the leading theoretical models for the CISS effect. Next, it identifies some implications of CISS in physics, chemistry, and biology. The discussion ends with a critical assessment of the CISS field and some comments on its future outlook.

“…By single-molecule junctions, there are numerous demonstrations about the electrical characterization and chemical reaction conducted in solution environments. 25–29 For example, Murakoshi et al reported the in situ observations of geometrical and electronic structural dynamics using mechanically controllable break junctions in aqueous solutions. 30 Luo et al measured the temperature-dependent conductance of single-molecule junctions in aqueous solutions and observed the thermal motion of water molecules.…”
