Abstract

We report the synthesis of a new set of amphiphilic saddle-shaped heptagon-containing polycyclic aromatic hydrocarbons (PAHs) functionalized with tetraethylene glycol chains and their self-assembly into large two-dimensional (2D) polymers. An in-depth analysis of the self-assembly mechanism at the air/water interface has been carried out, and the proposed arrangement models are in good agreement with the molecular dynamics simulations. Quite remarkably, the number and disposition of the tetraethylene glycol chains significantly influence the disposition of the PAHs at the interface and conditionate their packing under pressure. For the three compounds studied, we observed three different behaviors in which the aromatic core is parallel, perpendicular, and tilted with respect to the water surface. We also show that these curved PAHs are able to self-assemble in solution into remarkably large sheets of up to 150 μm. These results show the relationship, within a family of curved nanographenes, between the monomer configuration and their self-assembly capacity in air/water interfaces and organic-water mixtures.

摘要

我们报道了一组新的两亲性含七元环鞍形多环芳烃（PAHs）的合成，这些PAHs用四甘醇链进行了功能化修饰，并将它们自组装成大型二维（2D）聚合物。已对气/水界面处的自组装机制进行了深入分析，所提出的排列模型与分子动力学模拟结果高度吻合。非常值得注意的是，四甘醇链的数量和排列显著影响PAHs在界面处的排列，并决定它们在压力下的堆积情况。对于所研究的三种化合物，我们观察到三种不同的行为，其中芳香核相对于水面分别为平行、垂直和倾斜。我们还表明，这些弯曲的PAHs能够在溶液中自组装成尺寸显著大至150μm的薄片。这些结果表明，在一族弯曲的纳米石墨烯中，单体构型与它们在气/水界面和有机-水混合物中的自组装能力之间存在关联。
