Multicomponent Assembly of a Pyrazine-Pillared Coordination Cage That Selectively Binds Planar Guests by Intercalation

摘要

Aromatic intercalation is an important phenomenon both in chemistry and biology. When large aromatic molecules are intercalated, their chemical and physical properties are expected to change significantly. To exploit such unique properties, several molecular tweezers and boxes based on large π systems (for example, anthracene or porphyrin) have been developed, yet the precise construction of rigid, three-dimensional cages for efficient aromatic intercalcation still remains tedious.
