Nanostructures via noncovalent synthesis: 144 hydrogen bonds bring together 27 components.
This paper describes the spontaneous and reversible assembly of approximately 20 kDa synthetic hydrogen-bonded assemblies via the formation of 144 cooperative hydrogen bonds. These nanostructures ( approximately 3.0 x 5.5 nm), consisting of 27 different components, have been carefully characterized using a combination of (1)H NMR spectroscopy, MALDI-TOF MS using Ag(+)-labeling, gel permeation chromatography, and CD spectroscopy.
