A multifunctional Ni(ii) coordination polymer: synthesis, crystal structure and applications as a luminescent sensor, electrochemical probe, and photocatalyst

Abstract

Herein, a nickel coordination polymer (CP 1), {Ni(1,4-bib)(TPA-Cl)·HO} (1,4-bib = 1,4-bis(1H-imidazol-1-yl)benzene, HTPA-Cl = 2,5-dichloro-terephthalic acid), has been synthesized under solvothermal conditions. The structure of CP 1 is a 3D 3-fold interpenetrating framework with the sqc12 topology. The thermal stability and luminescence properties of CP 1 were investigated. Scanning electron microscopy (SEM) images of this material display that it possesses an irregular block 3D structure. Interestingly, CP 1 can serve as a multifunctional material via its luminescence sensing, electrochemical sensing, and photocatalytic properties. The experimental results indicate that CP 1 is an efficient luminescent sensor for the detection of Fe ions in an aqueous solution. In addition, CP 1 exhibits a sensitive and rapid electrochemical response to nitrite ions in water solution. The photocatalytic activities of CP 1 were evaluated in the degradation of different dye contaminants (MB, RhB, and MO), and the results demonstrate that its photocatalytic efficiency for the degradation of MB is highest (92.1% for MB, 85.7% for RhB, and 86.2% for MO). The effects of different dyes, different powers of UV light, and different amounts of catalyst CP 1 on the photocatalytic efficiency were also explored. Finally, the mechanism of the luminescence quenching effect toward Fe ions, electroreduction of nitrite ions, and photocatalytic degradation of different dyes have been investigated in detail.

“…Hence, 1 is vigorous for the decomposition of MB/MV under UV light irradiation. 2 can serve as an excellent candidate for decomposing MB . The PXRD patterns of the used 1 and 2 were almost identical to the patterns of the original samples (Figure S7).…”

“…2 can serve as an excellent candidate for decomposing MB. [56,57] The PXRD patterns of the used 1 and 2 were almost identical to the patterns of the original samples ( Figure S7). The results prove that both 1 and 2 are reproducible photocatalysts ( Figure S9).…”

Sensing and photocatalytic properties of nanosized Cu(I)CN organotin supramolecular coordination polymer based on pyrazine

“…In the last few decades considerable attention has been paid to the design and construction of new supramolecular coordination polymers (SCPs) not only for their intriguing structural motifs with unusual topologies and functional properties, but also for their various properties for application in the fields of host-guest chemistry, magnetism, gas storage, ion exchange, photocatalysis, bioinorganic chemistry, electrical conductivity, catalysis, nanosized reaction containers and so on. [1][2][3][4][5][6] Compared with the traditional self-assembly methods, [7][8][9][10] use of ultrasonic irradiation has recently been considered as a facile and environmentally friendly method for the formation of nanostructured SCPs [11] which exhibit superior properties. [12][13][14][15] Although sonochemical methods have been adopted for the preparation of nanomaterials, the application of the ultrasonic method for construction of SCPs has received relatively limited attention.…”
