Abstract

A functionalization of single-walled carbon nanotubes (SWCNTs) without the necessity to introduce defects to the atomic structure of the graphitic lattice can be achieved via π-stacking interaction of the SWCNTs sidewalls with aromatic molecules. In our work we study the functionalization of SWCNTs with two different aromatic molecules by scanning tunneling microscopy (STM) and scanning tunneling spectroscopy (STS Functionalization was performed in solution and the SWCNTs so obtained were transfered to a sputter-annealed Au(111) substrate using dry transfer techniques in vacuum to avoid surface contamination. Differential conductance imaging of the atomically resolved functionalized SWCNT reveals a substructure which can be attributed to the molecular orbitals of aminoanthracene. These findings are compared to the STM images obtained from the bare molecule prepared by thermal evaporation on a clean Au(111) surface which are interpreted with the help of quantum chemical calculations of the molecular orbital structure. © 2006 WILEY-VCH Verlag GmbH & Co.
