A metal–organic framework constructed using a flexible tripodal ligand and tetranuclear copper cluster for sensing small molecules†
Abstract
A new porous metal–organic framework (MOF) {[Cu4(OH)2(tci)2(bpy)2]·11H2O} (1) based on a tetranuclear copper cluster with intracluster antiferromagnetic interactions was synthesized. Quartz crystal microbalance (QCM) sensor studies reveal sensitive and selective sensing for small molecules.
