Graphene nanoribbons (GNRs) are narrow strips of graphene which have the zigzag or armchair edge structure. GNRs have recently been applied in many energy-related fields such as adsorbent, lithium-ion batteries and high-performance electronic devices. Also, the bottom-up molecular synthesis of GNRs has been tried to facilitate fabrication and size control. However, these GNRs suffer from aggregation due to strong π-π interactions. We envision that picket-fence groups, which are edge-functionalized as pendants, would prevent the GNRs’ planar structure from stacking and thus disperse well. In this study, we synthesized a novel GNR precursor with picket-fence groups, followed by AB-type Diels-Alder polymerization via the bottom-up method. We were confirmed by Brunauer-Emmett-Teller(BET) that the distance between the molecules and the surface area were increased according to the picket fence effect. Also the synthesized GNRs with picket-fence groups have mesopore structure. |
