METALLO COVALENT ORGANIC FRAMEWORKS

Abstract

Reticular materials like Covalent organic frameworks (COFs) and metal-organic frameworks (MOFs) have drawn significant attention due to their well-ordered structures, which are used for gas adsorption, catalysis, and energy storage. MOFs, composed of metal ions linked by organic molecules, offer a variety of metal-centric functionalities suitable for applications. However, their practical use is sometimes limited by weak coordination bonds. In contrast, COFs are known for their exceptional stability, crystallinity, and tunability, but their composition of lighter elements (H, B, C, N, O, Si) often results in limited functionalities.

The advent of metallo-covalent organic frameworks (metallo-COFs) marks an advancement in this field. These frameworks incorporate metal ions at pendant sites, combining the robust covalent linkages of COFs with the functional versatility of MOFs. This hybrid structure enhances the potential for creating innovative materials with sophisticated properties.

Our research has capitalized on metal-templated strategies to enhance synthetic efficiency and control topology and morphology.
