A series of metal organic frameworks-derived nanoporous carbons originating from zeolitic imidazolateframework-8 (ZIF-8) crystals as precursors have been prepared via varying the preparation conditions. TheZIF-8-derived carbons were subsequently admixed in the methacrylate monomers containing polymerizationmixtures and polymerized to obtain monolithic columns for capillary electrochromatography (CEC). The effectof particle size and content of the ZIF-8-derived carbon materials in the polymerization mixture on theperformance of the hybrid monolithic columns was investigated in detail. The resulting composites werecharacterized using scanning electron microscopy. Using short time UV-initiated polymerization, monolithicbeds with homogenously dispersed ZIF-8-derived carbons were obtained. The chromatographic performance ofthese composites was demonstrated with separations of polycyclic aromatic hydrocarbons and non-steroidalanti-inflammatory drugs as test solutes. The incorporation of the ZIF-8-derived carbons into the organicpolymer monoliths led to an increase in the retention of all the analytes compared to the parent monolith.Finally, the hybrid monolithic columns exhibited satisfactory run-to-run and batch-to-batch reproducibility.
