Metal-organic framework polymer for solid-phase microextraction

摘要

A metal-organic framework (MOF) polymer for solid-phase microextraction (SPME) includes an MOF including metal ions building units coordinating polytopic organic linkers; and a polymer coordinatively bonding to the MOF, wherein the polymer is composed of one or more vinyl monomers and a cross-linker those are polymerized in the presence of a radical initiator. A method for preparing a stationary phase for SPME is also provided.

1. A method for preparing a stationary phase for solid-phase microextraction (SPME), comprising:
providing capillary vinylization to an inner wall of a capillary tube; and preparing an metal-organic framework (MOF)-polymer by loading and mixing an organic monomer, a cross-linker, an initiator and a progenic solvent in the capillary tube, and then performing an polymerization reaction via heating of the capillary tube, wherein the MOF-polymer comprises:
an MOF including a plurality of metal ions building units coordinating a plurality of polytopic organic linkers; anda polymer coordinatively bonding to the MOF, the polymer being composed of one or more vinyl monomers and a cross-linker, wherein the one or more vinyl monomers and the cross-linker are polymerized in the presence of a radical initiator, wherein the MOF-polymer is used as a stationary phase for SPME.
