The formation of chiral nanostructures via molecular assembly and reaction on solid surfaces is a ubiquitous surface process due to the symmetry-breaking at 2D surface. Studying chirality during the adsorption, assembly, and reaction of molecules on 2D solid surfaces at molecular level not only sheds deep insights into the enantioselective heterogeneous catalysis, chiral recognition, origin and evolution of chirality, and many important physical chemistry processes but also provides an important strategy to create chiral nanostructures. Here, we give a survey of recent advances in chiral expression and control in molecular assemblies and reactions on surfaces. We firstly give a brief introduction to the general concepts of chiral molecular nanostructures on surfaces. And then we focus on the induction and control of chirality expressed in molecular assemblies. The recent developments in the control strategies such as chiral co-adsorber, chiral auxiliary, chiral solvent, chiral templated surfaces, as well as the underlying mechanism to achieve the chiral induction and amplification, are reviewed. After that, we review the studies of chirality expressed in on-surface synthesis which has been proved to be a promising strategy to fabricate covalently bonded low-dimensional nanostructures and materials. In this respect, we introduce the chiral expression in the intramolecular and intermolecular coupling reactions on surfaces. In addition, we survey the methods to steer the stereoselectivity of on-surface reactions including the design of precursor structure, steric hindrance effect, substrate, kinetic parameters et al. Finally, the future outlook in this field is discussed.

通过分子组装和反应在表面上分子纳米结构的手性:表现和控制

由于二维表面的对称性破坏,通过分子组装和固体表面反应形成手性纳米结构是一种普遍存在的表面过程。在分子水平上研究分子在二维固体表面上的吸附、组装和反应过程中的手性,不仅可以深入了解对映选择性多相催化、手性识别、手性的起源和演化以及许多重要的物理化学过程,而且还提供了一个重要的创建手性纳米结构的策略。在这里,我们对分子组装和表面反应的手性表达和控制的最新进展进行了调查。我们首先简要介绍了表面手性分子纳米结构的一般概念。然后我们专注于分子组装中表达的手性的诱导和控制。综述了手性共吸附剂、手性助剂、手性溶剂、手性模板化表面等控制策略的最新进展,以及实现手性诱导和放大的潜在机制。之后,我们回顾了表面合成中手性的研究,这已被证明是制造共价键合的低维纳米结构和材料的有前途的策略。在这方面,我们在表面的分子内和分子间偶联反应中引入了手性表达。此外,我们调查了控制表面反应立体选择性的方法,包括前体结构的设计、位阻效应、底物、动力学参数等。最后,讨论了该领域的未来前景。
