Chiral symmetry breaking in molecular adsorption at the solid/liquid interface by lateral geometric nanoconfinement is demonstrated. The chiral nanoconfinement is created at the interface of achiral covalently modified highly-oriented pyrolytic graphite and a racemate by in situ scanning probe lithography. Enantioselective adsorption of chiral molecules is achieved by adjusting the relative orientation between the nanoconfining walls and substrate symmetry direction.
通过横向几何纳米限域作用在固/液界面上实现了分子吸附的手性对称破缺。在非手性共价修饰的高取向热解石墨与外消旋体的界面处通过原位扫描探针光刻技术制备手性纳米限域结构。通过调节纳米限域壁与基底对称方向之间的相对取向，实现了手性分子的对映选择性吸附。
