Robust Molecular Bowl-Based Metal–Organic Frameworks with Open Metal Sites: Size Modulation To Increase the Catalytic Activity

Abstract

Herein, two stable lead(II) molecular-bowl-based metal-organic frameworks and their micro- and nanosized forms with open metal sites were presented. These materials could act as Lewis acid catalysts to cyanosilylation reaction. Moreover, the catalytic performances are size-dependent, with the catalyst with nanosized form being 1 order of magnitude more efficient than those with micro- and millisized forms.
