Hydroxyl and carboxyl group functionalized conjugated microporous nanomaterial as adsorbent for the solid-phase extraction of phenolic endocrine disrupting chemicals from freshwater fish samples.

Endocrine disruption chemicals (EDCs) in food can seriously harm human health. In this study, a hydroxyl and carboxyl group functionalized conjugated microporous nanomaterial (CMP) was prepared by Friedel-Crafts reaction and used as solid-phase extraction (SPE) adsorbent. A functionalized CMP based SPE combined with high performance liquid chromatography-diode array detection was built for the determination of phenolic EDCs from nine fish samples.

A novel porphyrin-based conjugated microporous nanomaterial for solid-phase microextraction of phthalate esters residues in children's food.

A novel porphyrin-based conjugated microporous polymer (PCMP) with microporous structure and nitrogen-rich pyrrole building blocks was synthesized. The PCMP was used as a coating material to prepare solid-phase microextraction (SPME) fibers by sol-gel technique. Due to the toxicity of the phthalate esters (PAEs) and the necessity for their sensitive determinations in some food samples, the SPME fiber was investigated for the extraction of eleven PAEs from six different children's milk beverages prior to their detection by gas chromatography-mass spectrometry.

Efficient solid-phase microextraction of twelve halogens-containing environmental hormones from fruits and vegetables by triazine-based conjugated microporous polymer coating.

A triazine-based conjugated microporous polymer (TCMP) was generated by introduced 1, 3, 5-triazine into conjugated microporous polymer network via Friedel-Crafts reaction. Under the optimum synthesis conditions, the obtained TCMP has a loose and porous structure. It was then used as a fiber coating material for solid-phase microextraction (SPME) of halogens-containing environmental hormones.

Preparation of phenylboronic acid based hypercrosslinked polymers for effective adsorption of chlorophenols.

Hypercrosslinked polymers (HCPs) have demonstrated effective adsorption capabilities because of their rich porosity and high specific surface area. However, the HCPs prepared with phenylboronic acid based compounds as monomers via Friedel-Crafts alkylation reaction have not been reported yet. Herein, four new HCPs with phenylboronic acid (PBA), 1,4-benzenediboronic acid, 4-hydroxyphenylboronic acid and 4-carboxyphenylboronic acid as the respective monomers were prepared for the first time.
