Investigating Chirality-Induced Spin Selectivity (CISS) at the molecular level offers a novel perspective, in between Chemistry and Physics, on this still not fully understood phenomenon. Indeed, the molecular approach offers an advantage point for understanding CISS by disentangling the role of chiral molecules from that of the surfaces. Here, we present an overview of experimental observations of CISS in electron transfer on isolated molecules in solution and the current status of theory to model the phenomenon. We discuss what is accomplished and which are the most important questions, and we propose experiments based on electron and nuclear magnetic resonance both to unravel open issues on the CISS effect in electron transfer and to apply it to quantum technologies.
在分子水平上研究手性诱导自旋选择性(CISS)为这一尚未完全理解的现象提供了一个介于化学和物理之间的全新视角。实际上,分子方法通过区分手性分子和表面的作用,为理解CISS提供了一个有利视角。在此,我们概述了溶液中孤立分子电子转移过程中CISS的实验观察结果以及用于模拟该现象的理论现状。我们讨论了已取得的成果以及最重要的问题,并提出基于电子和核磁共振的实验,以揭示电子转移中CISS效应的未解决问题,并将其应用于量子技术。
