A highly stable Zn9-pyrazolate metal–organic framework with metallosalen ligands as a carbon dioxide cycloaddition catalyst†
Abstract
A three-dimensional (3D) metal–organic framework constructed from unprecedented Zn9O2(OH)2(pyz)12 (pyz = pyrazolate) clusters and Ni(salen)-derived linkers was reported. The MOF exhibits high catalytic activity for CO2 cycloaddition reactions with excellent stability. The MOF catalyst can be recycled at least 15 times without loss of activity and the turnover number (TON) per Ni site can reach as high as 2887.
