Abstract

Two 2D Zn(II) coordination polymers, formulated as [Zn(μ₂-tdc)(μ-pmid)] (1), {[Zn(μ₂-tdc)(μ-pmmid)₂·4H₂O]}_n (2) (H₂tdc = 2,5-thiophenedicarboxylic acid, pmid = 1-(4-pyridylmethyl)imidazole; pmmid = 1-(4-pyridylmethyl)-2-methylimidazole) have been synthesized by reactions of Zn(OAc)₂·2H₂O and H₂tdc with flexibleN-(4-pyridylmethyl)imidazole derivatives under the mild reaction conditions and characterized by single-crystal X-ray diffraction and other physicochemical methods. Structure determination demonstrates compound 1 displays a 2-fold 2D → 2D parallel interpenetrating structure, while compound 2 shows a 2D non-interpenetrating network. These results reveal that the substitute group in such N-(4-pyridylmethyl)imidazole derivatives might be the main factor resulting in these interpenetrating/ non-interpenetrating structures.Furthermore, compounds 1 and 2 show different thermal stabilities and strong solid-state luminescence emissions.

由二羧酸噻吩和柔性N-(4-吡啶基甲基)咪唑衍生物组装的两种2D Zn(II)配位聚合物:合成、晶体结构和光致发光性质

两种2D Zn（II）配位聚合物，配方为[Zn（μ2-tdc）（μ-pmid = 2,5-噻吩二羧酸，pmid = 1-（4-吡啶基甲基）咪唑；pmmid = 在温和的反应条件下，Zn（OAc）2·2H2O和H2tdc与柔性N-（4-吡啶甲基）咪唑衍生物反应合成了1-（4-吡啶基甲基）-2-甲基咪唑，并用单晶X射线衍射等物理化学方法对其进行了表征。结构测定表明化合物1显示2倍2D → 2D平行互穿结构，而化合物2显示2D非互穿网络。这些结果表明，N-（4-吡啶甲基）咪唑衍生物中的取代基可能是导致这些互穿/非互穿结构的主要因素。此外，化合物1和2显示出不同的热稳定性和强固态发光发射。图形摘要

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.
