A mesoporous Zr-based metal-organic framework driven by the assembly of an octatopic linker

Metal-organic frameworks (MOFs) based on high-connected nets are generally very attractive due to their combined robustness and porosity. Here, we describe the synthesis of BCN-348, a new high-connected Zr-MOF built from an 8-connected (8-c) cubic Zr-oxocluster and an 8-c organic linker. BCN-348 contains a minimal edge-transitive 3,4,8-c eps net, and combines mesoporosity with thermal and hydrolytic stability. Encouraging results from preliminary studies on its use as a catalyst for hydrolysis of a nerve-agent simulant suggest its potential as an agent for detoxification of chemical weapons and other pernicious compounds. We present BCN-348, a new high-connected MOF built from an 8-c cubic Zr-oxocluster and an 8-c organic linker. BCN-348 shows a 3,4,8-c eps net, mesoporosity, hydrolytic stability, and acts as a catalyst for hydrolysis of a nerve-agent simulant.
