V. Paraschiv et al., Nanostructures via noncovalent synthesis: 144 hydrogen bonds bring together 27 components, J ORG CHEM, 66(25), 2001, pp. 8297-8301
This paper describes the spontaneous and reversible assembly of similar to
20 kDa synthetic hydrogen-bonded assemblies via the formation of 144 cooper
ative hydrogen bonds. These nanostructures (similar to3.0 x 5.5 nm), consis
ting of 27 different components, have been carefully characterized using a
combination of H-1 NMR spectroscopy, MALDI-TOF MS using Ag+-labeling, gel p
ermeation chromatography, and CD spectroscopy.
