Abstract

Graphical abstract: A functional 1D Co(II) coordination polymer (NCST-2 ) was synthesized under hydrothermal condition. Furthermore, NCST-2 can act as a fluorescence sensor for Fe 3+ in aqueous solution and further shows high photocatalytic activities for the degradation of MB. Abstract: A Co(II)-based ternary coordination polymer with formula {[Co(BTC)0.5 (L)(H2 O)]·3H2 O} n (NCST-2, NCST = North China University of Science and Technology) was constructed from 1, 2-bis(thiabendazol-1-ylmethyl)benzene (L) and butane-1, 2, 3, 4-tetracarboxylic acid (H4 BTC) under hydrothermal conditions.NCST-2 features a one-dimensional zigzag chain, which is further extended through OH⋯O hydrogen bond and π ⋯ π stacking interactions into a three-dimensional supramolecular network.NCST-2 exhibits highly selective and recyclable performance for the fluorescence sensing of Fe 3+ in aqueous solution with a linear detection range of 0–400 μM and a detection limit of 0.12 μM.NCST-2 displays high photocatalytic activities for degrading methylene blue (MB) under UV irradiation. The possible mechanism of the photodegradation towards MB was investigated in detail.
