Fluorographene, a two-dimensional derivative of graphene, is an excellent starting material for the synthesis of graphene derivatives. In this work, a one-step, substrate-free method for the asymmetric functionalization of fluorographene layers with hydroxyl groups by a facile nucleophilic substitution reaction is reported. Such a chemical modification occurs in a biphasic aqueous-organic system under mild conditions, leading to Janus graphene nanosheets functionalized by hydroxyl groups on one side and retaining fluorine atoms on the other. The reported experimental route paves the way for two-dimensional bifacial graphene templates, thus broadening the application potential of graphene materials.

Janus Fluorographene衍生物的一步合成。

石墨烯是石墨烯的二维衍生物，是合成石墨烯衍生物的极佳原料。在这项工作中，已报道了一种通过容易的亲核取代反应对带有羟基的氟石墨烯层进行不对称官能化的一步法，无底物的方法。这种化学修饰发生在温和条件下的两相水性有机体系中，导致Janus石墨烯纳米片的一侧被羟基官能化，而另一侧保留了氟原子。报道的实验路线为二维双面石墨烯模板铺平了道路，从而拓宽了石墨烯材料的应用潜力。
