Abstract:
In this work, a two-dimensional zinc(II) coordination polymer (Zn-CP, ۱) has been selected forconsecutive post-synthetic modifications. In the first step, the coordinated solvent was removed to createthe solvent-free structure Zn-CP-df (۲) with open-coordination or Lewis acid sites. Then, the solvent-freestructure ۲ was functionalized by ethylene diamine and ۱,۳-diamino propane to obtain aminefunctionalized structures Zn-CP-en (۳) and Zn-CP-DAP (۴), respectively containing Lewis base sites.Finally, Zn-CP-en was reacted with chlorosulfonic acid (ClSO۳H) to obtain Zn-CP-SO۳H (۵) withBronsted acid sites. The capability of compounds ۱-۵ in iodine sorption in both vapor and liquid phaseswas investigated in detail. The results show outstanding iodine capture for both amine functionalizedstructures Zn-CP-en (۱۰۰% wt) and Zn-CP-DAP (۲۰۴%) [۱-۴].
