摘要:
Complexation-induced changes in H-1 NMR chemical shift have been used to determine high-resolution three-dimensional structures of supramolecular complexes. The approach has been validated for a system in which the X-ray crystal structure of the complex can be compared with the optimised NMR structure, and the agreement is remarkably good (rmsd = 0.37 Angstrom). Determination of the solution structure of an H-bonded zipper complex is used to demonstrate the power of the approach in systems for which alternative tools for structure determination are not useful.
