研究目的
Investigating the synthesis, characterization, and application of a new organic?inorganic hybrid zinc phosphite carboxylate as a luminescent sensor for Fe3+ and Cr2O7 2?.
研究成果
A highly stable MOF compound was synthesized, showing excellent thermal stability and good resistance to aqueous solutions in the pH range of 3?11. It can behave as a luminescent sensor toward Fe3+ and Cr2O7 2? with high selectivity, presenting a new method for the development of stable MOF materials.
研究不足
The development of organic?inorganic hybrid zinc phosphite/phosphate carboxylates is still at its infant stage, with very rare compounds reported in the literature. The construction of new compounds remains a great challenge.
1：Experimental Design and Method Selection:
The compound was synthesized hydro(solvo)thermally from the reaction of H2L, Zn(NO3)2·6H2O, H3PO3, 2-(2-aminoethoxy)ethanol, and HF at 140 °C for 3 days.
2：Sample Selection and Data Sources:
Colorless plate crystals of compound 1 were obtained and characterized.
3：List of Experimental Equipment and Materials:
