| Abstract: | 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 planarity is not a prerequisite for recognition motifs for graphene. |
