Directed one-pot syntheses of enantiopure dinuclear silver(I) and copper(I) metallo-supramolecular double helicates
TL;DR: The dinuclear double helical structures were confirmed by single crystal X-ray analysis and their persistence in solution was supported by inter-strand NOE data as discussed by the authors, and they were also prepared by similar one-pot procedures and analysed by 1H NMR, mass spectrometry and circular dichroism.
