The supramolecular modification of planar graphene with the geometrically mismatched, curved 9,10‐di(1,3‐dithiole‐2‐ylidene)‐9,10‐dihydroanthracene (exTTF) molecule is demonstrated. The exTTF–graphene interaction is governed by π–π and CH–π interactions, with a negligible contribution from charge transfer. We amplified these weak forces through multivalent gold nanoparticles. Our results show that
证明了平面石墨烯的超分子修饰是几何上不匹配的弯曲的9,10-di(1,3-dithiole-2-yidene)-9,10-dihydroanthracene(exTTF)分子。exTTF-石墨烯相互作用受π-π和CH-π相互作用控制,电荷转移的贡献可忽略不计。我们通过多价金纳米颗粒放大了这些弱力。我们的结果表明,平面度并不是识别石墨烯的前提条件。
