The high performance separation and pre-concentration of polar phenols from aqueous matrices is difficult because of the strong interactions between phenols and water molecules. Conjugated micro-porous polymers (CMPs) are a kind of novel porous organic materials. Polyphenylene core-conjugated microporous polymers (PPc-CMPs) were used as a novel coating material in the solid-phase micro-extraction of polar phenols in water samples for the first time. The novel PPc-CMPs fibers exhibited good thermal stability (>450 degrees C), high enrichment factors (519-2372), low limits of detection (0.02-0.05 ng L-1), wide linearity (0.1-1000 ng L-1), and good repeatability (2.5%-8.1%) for polar phenols. The new coating was successfully used in the analysis of phenols in real environmental water samples. PPc-CMPs as a polar solid-phase microextraction coating material was excellent for the rapid and sensitive analysis of phenols at trace levels in the environment. (C) 2018 Elsevier B.V.
