石墨烯(或还原的石墨烯氧化物)作为原子模板和结构支架在有机纳米结构的成核和组装中具有双重作用。石墨烯和芳香族有机分子之间的π-π堆积作用提供了协同结合作用，主体和客体承担了原子模板和结构支架的互换角色。从在石墨烯模板上播种有机导线开始，生长出来的有机导线反过来充当一维支架，石墨烯薄片覆盖在周围，形成独特的石墨烯-有机杂化结构。利用这种π组装方法，我们合成了由石墨烯-N，N‘-二辛基-3，4，9，10-二苯甲酰亚胺有机导线组成的一维杂化结构。这种混合结构在供体-受体型(PDI-石墨烯/聚噻吩型)太阳能电池中表现出比其单独组件更好的性能。
The dual role of graphene (or reduced graphene oxide) as atomic template and structural scaffold in the nucleation and assembly of organic nanostructures is demonstrated. The π-π stacking interactions between graphene and aromatic organic molecules affords synergistic binding interactions, with the host and guest assuming the interchangeable roles of atomic template and structural scaffold. Beginning with the seeding of organic wires on graphene template, the outgrown organic wires in turn act as one-dimensional scaffolds where graphene sheets coat around to form a unique graphene-organic hybrid structure. Using this π-assembly approach, we have synthesized one-dimensional hybrid structures consisting of graphene-N,N'-dioctyl-3,4,9,10-perylenedicarboximide (PDI) organic wires. This hybrid structure shows enhanced performance over its individual components in donor-acceptor type (PDI-Graphene/polythiophene) solar cells.
