Post-synthetic metal exchange on an amine-functionalized zinc coordinationpolymer for hydrogen sulfide capture

Tandem post-synthetic modification is an interesting approach for improving the properties ofcoordination polymers. In this work, we report surface functionalization by amine group under ultrasoniccondition and tandem post-synthetic metal-exchange (PSE) on zinc coordination polymer (Zn-CP).During the metal exchange process Cu۲+ ions were replaced by Zn۲+ ions in methanol . Due to the existenceof two suitable sites in the obtained product, i.e. copper metal nodes and amine surface functional groups,it acquires the ability to enhance the hydrogen sulfide (H۲S) capture [۱-۳].
