Hexa‐ peri hexabenzocarbonate (HBC) are small cluster of a graphene plane with various side groups for stabilization. Due to theire ate geometry they are ideal candidates to study surface enhanced Raman spectroscopy (SERS). Very thin films HBC were vaopur deposited to different SERS‐active Ag‐surfaces. The enhancement of the Raman signal was studied with the goal to develop an Ag‐surface of optimum enhancement, for multiple use and very simple sample preparation. For the current surface the observed enhancement is up to 10 6 . For SWNT filled with Ag‐particles the SERS effect could also be shown – but enhancement was only a factor 10.
