A supramolecular double-helix based on complementary phosphate–guanidinium pairing†
Abstract
A double-helical supramolecular structure was formed by self-assembly of 1,1′-binaphthyl-based bisguanidines and bisphosphoric acids. Interestingly the homochiral (S,S) + (S,S)-pair forms a left-handed double-helix, while the heterochiral (S,S) + (R,R)-pair forms a non-helical dimer.
