After the publication of our paper we have become aware of the work of Nonappa, Lahtinen, Kolehmainen et al. reporting CP/MAS NMR spectra of gels. Hence, the sentence referring to CP/MAS NMR results should read ‘‘These are rare examples of supramolecular gels in which 1 H– 13 C CP/MAS NMR peaks were detectable without any physical modification of the gel samples.’’ 1–3 References 1 Nonappa, M.
