Abstract
Coordination polymers (CPs) represent a potentially highly valuable class of materials for next-generation applications in heavy metal removal and as antibacterial agents. Ligands bearing sulfur donors are ideal candidates for the preparation of CPs for these applications since sulfur atom has lone pairs of electrons which could be donated to some metal ions, thereby binding the metals selectively; and it is also effective in disrupting bacterial functioning. Herein, we report, the synthesis of the crystal (1crys) and the powder (1powd) forms of the Zn(II)-based CP [Zn(TDPA)2(TMPy)2]n (1) (where TDPA = 3,3-thiodipropionic acid and TMPy = 4,4-trimethylenedipyridine). Structural elucidation of the CPs – 1crys and 1powd were undertaken by means of FTIR, TGA and PXRD. The 1powd was obtained in much higher yields than the 1crys, and heavy metal removal behavior and antibacterial activity of the former were extensively investigated. Excellent removal capacities of 667 mg/g for Ag(I) and for Pb(II) by 1powd in single batch studies were observed. Additionally, 1powd inhibited the growth of six common bacterial strains and showed minimum inhibitory concentrations comparable to reported antibacterial agents. The efficiency of 1powd for these applications is linked to the sulfur-containing ligand used in the construction of the CP and its polymeric structure. Overall, the ease of preparation, yield, outstanding heavy metal removal capacities and potency in inhibiting bacterial growth offers 1powd as a highly adaptable and multifunctional material.
期刊介绍:
The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science.
Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
