The past decade has witnessed a fascinating marriage between polycyclic hydrocarbon chemistry and emerging physics. Interconnected benzene rings, namely graphene, gave rise to Dirac quasiparticles and fractionally-charged quasiparticles. These fields of Nobel recognition underlie well-known hydrocarbon chemistry notions, e.g. pi-conjugation, (hetero)aromaticity and multiradical character, to mention a few. As such, incorporating polycyclic hydrocarbon design principles into model 2D materials, might grant access to new paradigms in topological material design. In this joint Sino-German proposal, TU Dresden (TUD), a leader in heteroatom-doped nanographene chemistry, and long-term collaboration partners, who are leaders in fundamental and applied surface science, at the Institute of Physics of the Chinese Academy of Sciences (IoPCAS), want to establish a new field of research in heteroatom-doped cove and isoelectronic zigzag-edged, as well as antiaromatic nanographene science. The IoPCAS is known for having the largest availability of UHV surface science equipment world-wide. At the same time, German chemistry has played a pioneering role on UHV interfacial science while German physics known as active developers in avant-garde UHV techniques. This proposal aims at stimulating mobility of researchers between both countries within this key and strategic field of research and potential economical importance.All partners defined five key objectives:- Synthesis of doped (nitrogen and sulfur) cove edged graphene nanoribbons with tailored electronic properties- Synthesis of isoelectronic nitrogen-boron-nitrogen doped zigzag edged graphene nanoribbons- On-Surface generation and in situ investigation of antiaromatic N-doped nanographenes- Antiaromatic-N-doped graphene synthesis- In situ lateral transport measurmentsThe collaborative research project consists of the world-recognized scientists Prof. Xinliang Feng (TUD), Prof. Hong-Jun Gao (IoPCAS), Prof. Shixuan Du (IoPCAS), and Prof. Carlos Andres Palma (IoPCAS). Besides two internal Sino-German project workshops, an international, project related symposium with the participation of international renowned researchers of the field is planned. The total project duration is three years. The project is not covered by other financial supports such as EC Graphene Flagship.

过去十年见证了多环烃化学与新兴物理学之间令人着迷的结合。相互连接的苯环，即石墨烯，产生了狄拉克准粒子和分数带电准粒子。这些诺贝尔奖认可的领域是众所周知的碳氢化合物化学概念的基础，例如仅举几例，π-共轭、（异）芳香性和多自由基特征。因此，将多环烃设计原理纳入二维材料模型中，可能会为拓扑材料设计提供新的范式。在这项中德联合提案中，杂原子掺杂纳米石墨烯化学领域的领先者德累斯顿工业大学 (TUD) 和中国科学院物理研究所基础和应用表面科学领域的长期合作伙伴科学（IoPCAS）希望在杂原子掺杂凹坑和等电子锯齿形边缘以及反芳香纳米石墨烯科学方面建立一个新的研究领域。 IoPCAS 因拥有全球最大的特高压表面科学设备而闻名。与此同时，德国化学在特高压界面科学方面发挥了先锋作用，而德国物理学则被誉为特高压前卫技术的积极开发者。该提案旨在刺激两国研究人员在这一关键和战略研究领域以及潜在经济重要性方面的流动性。所有合作伙伴确定了五个关键目标：- 合成具有定制电子特性的掺杂（氮和硫）凹边石墨烯纳米带- 合成等电子氮-硼-氮掺杂锯齿形边缘石墨烯纳米带的制备-反芳香族氮掺杂纳米石墨烯的表面生成和原位研究-反芳香氮掺杂石墨烯合成-原位横向传输测量该合作研究项目由世界知名科学家冯新良教授（TUD）、高洪军教授（IoPCAS）、杜世轩教授（IoPCAS）和卡洛斯·安德烈斯·帕尔马教授 (IoPCAS)。除了两次内部中德项目研讨会外，还计划举办一次由该领域国际知名研究人员参加的国际项目相关研讨会。项目总工期为三年。该项目不受 EC 石墨烯旗舰等其他财务支持的覆盖。
