Abstract

Reaction of CuSO₄·5H₂O with 1,3-bis(benzimidazol-1-ylmethyl)-2,4,6-trimethylbenzene (m-bbitrb) provides a new positively charged M₂L₄ type molecule, [SO₄⊂Cu₂(m-bbitrb)₄]SO₄. This compound includes SO₄²⁻ inside and outside the cationic cage. Despite this compound being insoluble in water, it shows highly efficient perchlorate removal activity from water by the exchange with SO₄²⁻ outside the cage.
