Four new complexes, [Zn(TIBTC)(DMA)]·[NH2(CH3)2] (1), [Cd(TIBTC)(H2O)]·[NH2(CH3)2]·DMA (2), [Cd2(TIBTC)(2,2′-bipy)2(HCOO)] (3), and [Cd2(DIBTC)(2,2′-bipy)2(HCOO)] (4) (H3TIBTC = 2,4,6-triiodo-1,3,5-benzenetricarboxylic acid, H3DIBTC = 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 1 and 2 are three-dimensional supramolecular network structures, while complex 4 has a two-dimensional network structure. We preliminarily studied the fluorescence properties of the complexes and found that complexes 1-3 can detect thiamine hydrochloride, NACs, and Fe3+/Zn2+ with high sensitivity and selectivity.

- A family of functional Ln-organic framework constructed by iodine-substituted aromatic polycarboxylic acid for turn-off sensing of UO22+

With the rapid development of nuclear energy, one of the main constraints restricting the development of nuclear energy is the long-term safe disposal of strong uranium waste. Here it is a great significance that we use four new synthetic Ln (III)-based coordination polymers to test the uranium solution. In this study, four three-dimensional coordination polymers 1–4 (CPs-(1–4); Ln?=?Eu, Gd, Sm, Nd) were successfully synthesized through 1:1 complexation of Ln (NO3)3·6H2O with poly-carboxylic acid ligand H3TIBTC (2,4,6-Triiodo-1,3,5-benzene tricarboxylic acid) which contains substituents of the carboxylic acid group and halogen atom, respectively. Based on the ligand being excellent fluorescent properties in the solution, it prompted us to further study the fluorescence properties of the coordination polymers. Experimental results show that the coordination polymers are favorable materials for the simultaneous selective detection uranium solution from water, being potentially useful in monitoring water quality and treating uranium-wastewater.

Poly[tris(dimethylformamide)(μ3-2,4,6-triiodol-1,3,5-benzene tricarboxylic acid)-praseodymium (III)] {Pr(TIBTC)(DMF)3}n (1) (H3TIBTC = 2,4,6-triiodo-1,3,5-benzene tricarboxylic acid) was synthesized by the reaction of Pr(NO3)3·6H2O and H3TIBTC at 85°C in a pyrex vial. 1 was characterized by elemental analysis, IR, UV–vis, TGA, PXRD, and atomic force microscopy analytical means. Each of the central Pr ions and the three carboxyl groups from the same ligand constitute a SBU, which is then joined by a carboxyl group to form a building block. In order to further explore the functional properties of 1, we used this compound for adsorption experiments. It is found that 1 can effectively adsorb anionic dyes in aqueous solutions. In particular, there is a good adsorption efficiency for coomassie brilliant blue R-250. Therefore, 1 shows good prospects for selective adsorption of anionic dyes from wastewater solution.
