Pillars of self-assembled pyridyl bis-urea macrocycle as a halogen bond acceptor

What is it about?

Halogen bonding is an important tool to control the organization of small molecules into supramolecular assemblies, producing superior properties for materials that have applications in areas as diverse as non-linear optics (NLO) and pharmaceuticals.

Why is it important?

In this work, we have established the ability of the pillars of assembled pyridyl bis-urea macrocycle (host 1) to absorb and organize small organic molecules in the solid-state through non-covalent interactions.
