“…Two distinct enantiomers, namely (R)- (+) - α - methylbenzylamine ( R -MBA) and ( S )-(−)-α-MBA ( S -MBA), have previously been employed as SPs 29 , 30 . The S -MBA SP exhibits a significantly improved CISS efficiency of 65% compared to other previously reported chiral catalysts 23 . However, due to the comparatively weak helicity of the MBA organic cation arrangement, its spin-orbital coupling (SOC) essentially determined by the geometry of chiral organic ligands needs to be enhanced 31 .…”

“…Despite the promising potential of chiral molecules used as a CISS enabler in their electrochemistry, limited performance is likely encountered in photoanodes coated with slow polaron-hopping mediated organic catalysts 21 , 22 . In order to enhance the low catalytic activity of organic chiral catalysts, a chirality-transferred CoO x catalyst has been developed to improve the OER performance of BiVO 4 photoanode 23 . However, such a photoanode generally exhibits a low photocurrent and high overpotential because the oxide semiconductor absorber retains poor light harvesting ability and electrical conductivity.…”

The oxygen evolution reaction, which involves high overpotential and slow charge-transport kinetics, plays a critical role in determining the efficiency of solar-driven water splitting. The chiral-induced spin selectivity phenomenon has been utilized to reduce by-product production and hinder charge recombination. To fully exploit the spin polarization effect, we herein propose a dual spin-controlled perovskite photoelectrode. The three-dimensional (3D) perovskite serves as a light absorber while the two-dimensional (2D) chiral perovskite functions as a spin polarizer to align the spin states of charge carriers. Compared to other investigated chiral organic cations, R-/S-naphthyl ethylamine enable strong spin-orbital coupling due to strengthened π–π stacking interactions. The resulting naphthyl ethylamine-based chiral 2D/3D perovskite photoelectrodes achieved a high spin polarizability of 75%. Moreover, spin relaxation was prevented by employing a chiral spin-selective L-NiFeOOH catalyst, which enables the secondary spin alignment to promote the generation of triplet oxygen. This dual spin-controlled 2D/3D perovskite photoanode achieves a 13.17% of applied-bias photon-to-current efficiency. Here, after connecting the perovskite photocathode with L-NiFeOOH/S-naphthyl ethylamine 2D/3D photoanode in series, the resulting co-planar water-splitting device exhibited a solar-to-hydrogen efficiency of 12.55%.

“…In subsequent studies with helically aggregated dye molecules additional features of spin polarization on the characteristics of water splitting became apparent; not only was spin polarization responsible for decreasing the reaction overpotential for the OER, it was shown to inhibit the formation of hydrogen peroxide, as well as other super oxides . These effects have since been shown for other chiral catalysts, − including chiral metal oxides ,,,− and metal sulfides. , As an aside, we note that CISS may account, in part, for the high activity of photosystem II …”

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.

To facilitate the transition from a carbon‐energy‐dependent society to a sustainable society, conventional engineering strategies, which encounter limitations associated with intrinsic material properties, should undergo the paradigm shift. From a theoretical viewpoint, the spin‐dependent feature of oxygen evolution reaction (OER) reveals the potential of a spin‐polarization strategy in enhancing the performance of electrochemical (EC) reactions. The chirality‐induced spin selectivity (CISS) phenomenon attracts unprecedented attention owing to its potential utility in achieving novel breakthroughs. This paper starts with the experimental results aimed at enhancing the efficiency of the spin‐dependent OER focusing on the EC system based on the CISS phenomenon. The applicability of spin‐polarization to EC system is verified through various analytical methodologies to clarify the theoretical groundwork and mechanisms underlying the spin‐dependent reaction pathway. The discussion is then extended to effective spin‐control strategies in photoelectrochemical system based on the CISS effect. Exploring the influence of spin‐state control on the kinetic and thermodynamic aspects, this perspective also discusses the effect of spin polarization induced by the CISS phenomenon on spin‐dependent OER. Lastly, future directions for enhancing the performance of spin‐dependent redox systems are discussed, including expansion to various chemical reactions and the development of materials with spin‐control capabilities.
