  • The authors gratefully acknowledge Dr. F. Hennrich and Prof. M. Kappes (Universität Karlsruhe) for providing SWNTs produced by a laser-ablation method, and Dr. Y. Joseph (Materials Science Laboratory) for XPS measurements of U-SWNTs from entry 9 and the UA-SWNTs from entry 8 (Table 1).

Abstract

Water-soluble single-walled carbon nanotubes are readily prepared by treating oxidatively purified nanotubes with molten urea. Evidence is provided for appended amido and ureido groups in the product (see figure), which can be further modified by condensation reactions if p-anisaldehyde is added during the process.
