Guest-Responsive Function of a Dynamic Metal-Organic Framework with a π Lewis Acidic Pore Surface

Abstract

A 3D dynamic coordination framework with an electron-deficient pore surface has been synthesized by using ZnII (having a variable coordination number) and a predesigned flexible π-electron-deficient core-based ligand, exhibiting chemical separations based on pore surface functionalization (π Lewis acidic pore surfaces and open metal sites) and framework flexibility, giving rise to a unique smart guest-responsive material.
