Application of microporous organic networks in separation science

Microporous organic networks (MONs) are a new class of advanced porous materials built from versatile aromatic alkynes and halides via Sonogashira coupling. The extremely large surface areas, excellent solvent and thermal stabilities, tunable pore sizes and functions, as well as convenient post-modification and easy engineering on other matrices make MONs highly convincing in analytical chemistry from sample pretreatment to chromatographic separation. This review briefly introduces recent application and progress of MONs and MONs-based composites in separation science including solid phase extraction, solid phase microextraction, gas chromatography and high-performance liquid chromatography. In the end, the challenge and outlook about the application of MONs in separation science are also presented.
