Supramolecular assembly requires molecular-scale engineering, and organic chemists are becoming smarter at designing and building the functional sub-components that hold these features together. Lipid bilayers are classic supramolecular assemblies, but the interactions between individual molecules are not very strong. However, by providing synthetic head groups that lock far more tightly, strongly associated structures can be engineered. The tetraaza heart of compound (1) is bent back so that the fused dimethoxyaryl features are held Out like welcoming arms, as sketched in (2) (see Figure 1)...
