Abstract:
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.
摘要:
Helicenes是一类重要的手性有机材料,具有很好的光电性能。因此,用螺旋烯对表面进行功能化是迈向新型有机材料器件的关键步骤。这篇综述介绍了具有不同螺旋物种的金属表面的吸附和改性的不同方面。主题是手性结晶,也就是说,二维砾岩与外消旋体结晶,打破外消旋体的镜像对称性,手性诱导的自旋选择性,和立体选择性表面化学。
