Abstract

A new two-dimensional zeolitic imidazolate framework (named as ZIF-L) was synthesized in zinc salt and 2-methylimidazole (Hmim) aqueous solution at room temperature. ZIF-L (Zn(mim)₂·(Hmim)_1/2·(H₂O)_3/2 or C₁₀H₁₆N₅O_3/2Zn) has unique cushion-shaped cavities and leaf-like crystal morphology, and exhibits excellent CO₂ adsorption properties.
