Four new complexes, [Zn(TIBTC)(DMA)]·[NH(CH)] (), [Cd(TIBTC)(HO)]·[NH(CH)]·DMA (), [Cd(TIBTC)(2,2'-bipy)(HCOO)] (), and [Cd(DIBTC)(2,2'-bipy)(HCOO)] () (HTIBTC = 2,4,6-triiodo-1,3,5-benzenetricarboxylic acid, HDIBTC = 2,4-diiodo-1,3,5-benzenetricarboxylic acid, 2,2'-bipy = 2,2'-bipyridine, and DMA = dimethylacetamide), were successfully synthesized and characterized by elemental analysis, powder X-ray diffraction, infrared spectroscopy, ultraviolet-visible spectroscopy, and thermogravimetric analysis. Complexes and are three-dimensional supramolecular network structures, while complex has a two-dimensional network structure. We preliminarily studied the fluorescence properties of the complexes and found that complexes can detect thiamine hydrochloride, NACs, and Fe/Zn with high sensitivity and selectivity.
四种新配合物，[Zn(TIBTC)(DMA)]·[NH(CH)] ()，[Cd(TIBTC)(HO)]·[NH(CH)]·DMA ()，[Cd(TIBTC)(2,2'-bipy)(HCOO)] () 和 [Cd(DIBTC)(2,2'-bipy)(HCOO)] ()（HTIBTC = 2,4,6-三碘-1,3,5-苯三甲酸，HDIBTC = 2,4-二碘-1,3,5-苯三甲酸，2,2'-bipy = 2,2'-联吡啶，DMA = 二甲基乙酰胺），通过元素分析、粉末 X 射线衍射、红外光谱、紫外可见光谱和热重分析成功合成并进行了表征。配合物 和 具有三维超分子网络结构，而配合物 具有二维网络结构。我们初步研究了配合物的荧光性质，发现配合物 可以高灵敏度和选择性地检测盐酸硫胺素、NACs 和 Fe/Zn。
