The project focuses on spatially defined covalent and non-covalent functionalization of synthetic carbon allotropes (SCAs) and their optical and vibrational properties. We will develop different routes for spatially patterning the reactivity of graphene and CNT, e.g. by patterning the underlying substrate. Furthermore, non-covalent interactions in SCAs will be studied, in particular in diamondoid derivatives, in inter-SCA architectures, such as twisted bilayer graphene and PAHs, and in nanographene networks on surfaces. Based on fundamental understanding obtained with resonant Raman spectroscopy, Raman mapping, and TERS, our goal is to gain spatial control over covalent and non-covalent interactions in SCAs.

该项目的重点是合成碳同素异形体（SCA）的空间定义的共价和非共价官能化及其光学和振动特性。我们将开发不同的途径来空间图案化石墨烯和CNT的反应性，例如通过图案化底层衬底。此外，SCA中的非共价相互作用将被研究，特别是在金刚烷衍生物中，在SCA间架构中，如扭曲的双层石墨烯和多环芳烃，以及在表面上的纳米石墨烯网络中。基于共振拉曼光谱，拉曼映射，和TERS获得的基本理解，我们的目标是获得空间控制的共价和非共价相互作用的SCA。
