Planar and Bowl-shaped Electron-poor Polycyclic Aromatic Hydrocarbons

扩展多环芳烃（PAHs），也被称为纳米石墨烯，已成为有机功能材料领域的一个令人兴奋的研究领域。继富电子多环芳烃领域已经很发达，我们在这个项目中的主要目标是新的二维平面和碗状多环芳烃轴承吸电子酰亚胺基团的发展。基于在第一个资助期内成功开发所需分子框架的合成方法，我们未来几年的主要目标是阐明这些新型多环芳烃的具体性质。我们在这里的重点是超分子化学，我们设想基于我们的初步研究独特的可能性。我们将研究多酰亚胺功能化的多环芳烃和富电子多环芳烃之间的供体-受体络合物，超分子络合物如G-四联体在扩展的π-支架上的配位（模板效应），超分子聚合物和嵌段共聚物以及多环芳烃中离子与定制空腔的络合。

Extended polycyclic aromatic hydrocarbons (PAHs) that are also termed nanographenes have become an exciting research area in the field of organic functional materials. Subsequent to the already well-developed field of electron-rich PAHs our major objective in this project is the development of new two-dimensional planar and bowl-shaped PAHs bearing electron-withdrawing imide groups. Based on the successful development of synthetic methodologies for the desired molecular frameworks in the first funding period, our main goal for the next years is to elucidate the specific properties of these new types of PAHs. Our focus here is on supramolecular chemistry where we envision unique possibilities based on our preliminary studies. We will investigate donor-acceptor complexes between multiimide-functionalized PAHs and electron-rich PAHs, the coordination of supramolecular complexes such as G-quartets on the extended pi-scaffolds (template effect), supramolecular polymers and block co-polymers as well as the complexation of ions in PAHs with tailored cavities.
