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.

一种含硫配位聚合物:具有显著的重金属去除能力和广谱抗菌活性
配位聚合物(CPs)在下一代重金属去除和抗菌剂应用中具有潜在的高价值。携带硫给体的配体是这些应用中制备CPs的理想候选者,因为硫原子具有孤对电子,可以给一些金属离子,从而选择性地结合金属;它还能有效地破坏细菌的功能。本文报道了Zn(II)基CP [Zn(TDPA)2(TMPy)2] n(1)晶体形式(1crys)和粉末形式(1powd)的合成(其中TDPA = 3,3-硫代二丙酸,TMPy = 4,4-三亚甲二吡啶)。通过FTIR、TGA和PXRD对CPs - 1crys和1powd进行了结构分析。研究结果表明,前者的产率远高于后者,并对前者的重金属去除性能和抗菌活性进行了广泛的研究。在单批试验中,1powd对Ag(I)和Pb(II)的去除率达到667 mg/g。此外,1powd抑制6种常见细菌菌株的生长,并显示出与报道的抗菌剂相当的最低抑制浓度。1powd在这些应用中的效率与构建CP及其聚合物结构中使用的含硫配体有关。总之,易制备,产量,突出的重金属去除能力和抑制细菌生长的潜力使1powd作为一种高适应性和多功能材料。图形抽象

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.
