英文摘要： Due to their great performances, carbon nanomaterials have drawn many attentions in materials science. In this project, a series of fullerene derivatives will be designed and synthesized so as to improve the solubility, phase, stability, and interfacial assembly behaviors. Moreover, taking advantage of the unique properties of graphene, such as high electron mobility and 2D structure, the fullerene derivative-graphene assembly will be constructed based on non-covalent interaction. The correlations between the interfacial structure/interaction and the photoelectronic conversion performance, and the involved mechanism as well, will be investigated. It is highly anticipated that this project will greatly benefit the applications of carbon nanomaterials for new optoelectronic devices, and further expanding their applications in fields of analytical chemistry and sustainable energy, both in experiments and theories.
