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, {[Zn3(L)2(DABCO)­(H2O)]·9DMF} (named as Zn-1), has been synthesized based on [1,1′:3′,1″-terphenyl]-4,4″,5′-tricarboxylic acid (H3L) a...

Description
Summary: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, {[Zn3(L)2(DABCO)­(H2O)]·9DMF} (named as Zn-1), has been synthesized based on [1,1′:3′,1″-terphenyl]-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, {[Cu3(L)2(DABCO)­(H2O)]·15H2O·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.
