报告摘要 |
Graphene, the mother of all other graphitic carbons, has demonstrated exceptional physical properties such as high charge carrier mobility, room-temperature quantum Hall effect, good optical transparency and high mechanical and thermal stability, which lead to many prominent electronic applications. Yet, the future research of graphene calls for the efficient chemical synthesis of graphene at the different length and layer scales. Here we introduce a novel carbon-rich precursor approach towards the fabrication of well-defined graphene and carbon materials with tailorability at the molecular level. This strategy can further establish the link between 2D (graphene) and 3D carbon materials through the controlled pyrolysis of precursors in confining template or carbonmesophase state. Therefore, this method stands in contrast to other chemical means of carbon synthesis in terms of its 1) size, shape and component fine control; 2) structural perfection and 3) feasible processability. Prominent applications have been achieved with using these graphene and carbon materials as well as their carbon-metal nanocomposite across the ranges of transparent electrode, catalysis, sensing, supercapacitors and batteries. |

报告人简介：⑴现在工作单位及职称 ⑵主要研究方向 ⑶学术成就简述（100字以内）
He received his Bachelor’s degree in analytic chemistry from China University of Geosciences in 2001. Then he obtained his Master’s degree of organic chemistry from Shanghai Jiao Tong University in March 2004, where he worked on the synthesis of fluorinated ion-exchange resins and polymer-supported organic catalysis. Later on he moved to Prof. H. Mayr’s group at the University of Munich in April 2004 for a short period research on the nucelofugality and electrofugality in organic solvolysis. In September 2004, he joined the group of Prof. K. Müllen at the Max Planck Institute for Polymer Research for PhD thesis on the synthesis and supramolecular chemistry of novel polycyclic aromatic hydrocarbons, where he obtained his PhD degree in April 2008. Since December 2007, he was appointed as project leader at the Max Planck Institute for Polymer Research.
His current scientific interests include the synthesis and self-organization of extended graphene molecules, novel conjugated oligomers and polymers, and testing for applications in organic electronic devices, processable graphene sheets for transparent electrodes and organic electronics, functional organic nanomaterials for energy oriented application, graphene-based 2D nanomaterials and low-dimensional nanostructured functional carbon-rich as well as hybrid materials for energy storage and conversion.
