MOF side chains as sources of supramolecular interactions: organic pollutant extraction from water

Abstract

Polyethylene glycol-modified terphenyl tetracarboxylic ligands were used for the preparation of copper-based MOFs: SUM-102 and SUM-103. The influence of side chains on the stability and adsorption capacities was investigated. Compared to the simpler analogue-NOTT-101, these MOFs, in particular SUM-103, exhibit high stability in water. Also, side chains do not affect the thermostability. The extraction capacity of organic cationic and anionic dyes was demonstrated by adsorption experiments carried out in water. SUM-103 showed a high Langmuir adsorption capacity of methylene blue in an aqueous solution (194 ± 4 mg g−1 at 30 °C).
