Zinc(II) and Copper(II) Hybrid Frameworks via Metal-Ion Metathesis with Enhanced Gas Uptake and Photoluminescence Properties
The fabrication of metal organic frameworks with controlled structure and desired properties is important but still a challenge. In this work, a zinc(II) framework, {[Zn-3(L)(2)(DABCO)(H2O)]center dot 9DMF} (named as Zn-1), has been synthesized based on [1,1':3',1"-terpheny1]-4,4",5'-tricarboxylic acid (H3L) and 1,4-diazabicyclo[2.2.2]octane (DABCO), which is isostructural to the previously reported copper(II) analogue, {[Cu-3(L)(2)(DABCO)(H2O)]center dot 15H(2)0 center dot 9DMF} (named as Cu-1). Interestingly, hybrid zinc(II) and copper(II) bimetallic frameworks have been obtained via metal-ion metathesis and found to show enhanced adsorption and photoluminescence properties. Such a post metal-ion metathesis method can be used to synthesize new and desired frameworks that could not be obtained by direct synthesis.
