Two coordination polymers (CPs) with a novel bifunctional ligand, [ZnL]n (1) and [CdL(H2O)]n (2), (L = rigid 6-(1H-tetrazol-5-yl)-2-naphthoic acid), have been synthesized and structurally characterized, which reveal that the two constructed CPs exhibit three dimensional structures. The two CPs consist of a one-dimensional Zn-tetrazole chain and a double-layered two-dimensional Cd-tetrazole structure. In addition, IR, elemental analysis, and luminescent spectra of 1 and 2 were also examined. At room temperature, 1 exhibits an intense emission at around 421 nm upon 370 nm excitation, whereas 2 exhibits an intense emission at 381 nm upon 350 nm excitation. Through variable-temperature luminescent and quantum calculations, the blue-shift of the peaks from the ligand and 1 and 2 is ascribed to the different configurations of L caused by the different coordination environments of the metal ions.

Paragraph 0034; 0040; 0046, (2017/10/27)
The invention discloses a cadmium salt fluorescent functional coordination material and a preparation method thereof. The preparation method of the cadmium salt fluorescent functional coordination material includes steps: 1) reaction liquid preparation, to be more specific, adding 6-(1H-tetrazole-5-yl)-2-naphthoic acid and cadmium salt into a solvent, and well stirring for dissolution at a normal temperature to obtain reaction liquid; 2) crystallization reaction, to be more specific, putting the reaction liquid obtained at the step 1) in a drying oven at 135-145 DEG C to react for 10-14h to obtain clear crystal blocks, and sequentially filtering and washing to obtain the cadmium salt fluorescent functional coordination material. The cadmium salt fluorescent functional coordination material is formed by self-assembly coordination of the cadmium salt and 6-(1H-tetrazole-5-yl)-2-naphthoic acid, stable in humidity and temperature and excellent in fluorescent characteristic.

A novel "one-pot" reaction was developed for the synthesis of aryl or heteroaryl-substituted amidoxime compounds containing various functional groups. Fluorescence titration experiments coupled with theoretical analysis revealed that the steric hindrance and electronic effects of substituents influence the binding ability of the amidoxime compounds to uranyl ions.
