摘要

由于二维表面的对称性破坏,在固体表面上通过分子组装和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的吸附、组装和反应过程中的手性,不仅可以深入了解手性的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,而且为创建手性纳米结构提供了重要的策略。在这里,我们给出了手性表达和控制分子组装和表面反应的最新进展的调查。本文首先简要介绍了表面上的手性分子纳米结构的一般概念。然后我们将重点关注手性在分子组装中的诱导和控制。综述了近年来手性共吸附剂、手性助剂、手性溶剂、手性模板表面等控制策略的研究进展,以及实现手性诱导和扩增的机理。然后,我们回顾了手性在表面合成中的研究,手性已被证明是制造共价键低维纳米结构和材料的一种很有前途的策略。在这方面,我们介绍了表面分子内和分子间偶联反应中的手性表达。此外,我们还从前驱体结构设计、位阻效应、底物设计、动力学参数等方面综述了控制表面反应立体选择性的方法。最后,对该领域的发展前景进行了展望。

Chirality of molecular nanostructures on surfaces via molecular assembly and reaction: manifestation and control

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.

期刊介绍: Surface Science Reports is a journal that specializes in invited review papers on experimental and theoretical studies in the physics, chemistry, and pioneering applications of surfaces, interfaces, and nanostructures. The topics covered in the journal aim to contribute to a better understanding of the fundamental phenomena that occur on surfaces and interfaces, as well as the application of this knowledge to the development of materials, processes, and devices. In this journal, the term "surfaces" encompasses all interfaces between solids, liquids, polymers, biomaterials, nanostructures, soft matter, gases, and vacuum. Additionally, the journal includes reviews of experimental techniques and methods used to characterize surfaces and surface processes, such as those based on the interactions of photons, electrons, and ions with surfaces.
