Crystallographic evidence for the host-guest interaction of metallamacromolecules (A highlight review)

Abstract

Metallamacromolecules offer opportunities to create structural diversity and interesting properties based on their unique frameworks and host-guest chemistry. Various types of assemblies can be created by the appropriate choice of the predesigned organic ligands containing various backbones and connectivity information and metal centers. These macrocyclic hosts contain a large and tunable hydrophobic inner cavity, which can be able selectively to recognize guest molecules. The goal of this highlight review is to describe the synthetic routes for the preparation of metallamacromolecules including stepwise and self-assembly strategies as well as their molecular recognition properties.
