Narcissistic self-sorting in anion-coordination-driven assemblies

Three tris-bis(urea) ligands with triphenylamine-based C 3 -symmetric spacers were synthesized, which assembled with sulfate or phosphate to form anionic A 3 L 2 pinwheel helices (A = anion and L = ligand) and A 4 L 4 tetrahedra, respectively. Interestingly, narcissistic self-sorting was observed in...

Description
Summary:Three tris-bis(urea) ligands with triphenylamine-based C 3 -symmetric spacers were synthesized, which assembled with sulfate or phosphate to form anionic A 3 L 2 pinwheel helices (A = anion and L = ligand) and A 4 L 4 tetrahedra, respectively. Interestingly, narcissistic self-sorting was observed in both structures from the mixture of the ligands, wherein each assembly contains only one type of ligand with no detectable mixed-ligand product as confirmed by the NMR and MS studies. Narcissistic self-sorting was observed in the A 3 L 2 and A 4 L 4 assemblies of three tris-bis(urea) ligands with a sulfate or a phosphate anion.
