Overview

Mechanistic study reveals counteranion-driven iodine capture in hexacationic imidazolium organic cages, suggesting a tunable design strategy for nuclear waste remediation.

Key Points

To synthesize a hexacationic imidazolium organic cage and determine how altering its counteranions influences the efficiency and mechanisms of radioactive iodine capture.
Synthesized a hexacationic imidazolium organic cage via facile chemical synthesis.
Evaluated iodine capture capacities across cages paired with different counteranions.
Identified molecular-level iodine binding configurations using single-crystal X-ray crystallographic analysis of iodine-loaded cages.
Iodine capture behavior varied substantially depending on which counteranions were present in the cage system.
High iodine uptake was driven by a synergistic non-covalent network comprising hydrogen bonds, halogen bonds, anion···π interactions, and electrostatic interactions between polyiodides and the hexacationic cage framework.
