A supramolecular double-helix based on complementary phosphate-guanidinium pairing

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.

Automated summary

Self-assembly of 1,1'-binaphthyl-based bisguanidines and bisphosphoric acids forms a double-helical supramolecular structure, with homochiral pairs forming a left-handed double helix and heterochiral pairs forming a non-helical dimer.
