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.
