Abstract

A hybrid zeolitic imidazolate framework having an isolated purity of at least 95 wt. %, which is a coordination product formed between zinc(II) ions, a linker of formula (I), and a linker of formula (II); wherein each linker of formulae (I) and (II) links together adjacent zinc(II) ions, R1 and R2 are independently a hydrogen, an optionally substituted alkyl, an optionally substituted aryl, a halo, a nitro, or a cyano, and R3 and R4 are independently hydrogen, an optionally substituted alkyl, an optionally substituted aryl, or an optionally substituted arylalkyl. A method of making the hybrid zeolitic imidazolate framework and a method of capturing CO2 from a gas mixture with the hybrid zeolitic imidazolate framework.
