摘要

螺旋烯是一类重要的手性有机材料，具有良好的光电特性。因此，用螺旋烯对表面进行功能化是实现新型有机材料器件的关键一步。本综述介绍了金属表面吸附和改性不同螺旋烯种类的不同方面。涉及的主题包括手性结晶，即二维凝聚态结晶与外消旋体结晶、外消旋体镜像对称性的破坏、手性诱导的自旋选择性以及立体选择性表面化学。

Helicenes on Surfaces: Stereospecific On-Surface Chemistry, Single Enantiomorphism, and Electron Spin Selectivity

Helicenes represent an important class of chiral organic material with promising optoelectronic properties. Hence, functionalization of surfaces with helicenes is a key step towards new organic material devices. This review presents different aspects of adsorption and modification of metal surfaces with different helicene species. Topics addressed are chiral crystallization, that is, 2D conglomerate versus racemate crystallization, breaking of mirror-symmetry in racemates, chirality-induced spin selectivity, and stereoselective on-surface chemistry.

期刊介绍： The main aim of the journal is to publish original contributions of scientific work on the role of chirality in chemistry and biochemistry in respect to biological, chemical, materials, pharmacological, spectroscopic and physical properties. Papers on the chemistry (physiochemical, preparative synthetic, and analytical), physics, pharmacology, clinical pharmacology, toxicology, and other biological aspects of chiral molecules will be published.
