摘要: 研究了某些DMF和DMSO配位的金属十聚钨酸盐在 3 种有机溶剂中的光致变色性质,通过ESR、NMR和可见吸收光谱的研究及对五价钨的测定,说明了光致变色性质的产生与金属阳离子无关,而取决于十聚钨酸根W10O324-、金属离子的配体及所采用溶剂。

Abstract: The photochromism of some DMF and DMSO coordinated metal decatungstates in DMF DMSO, and acetonitrile has been studied through ESR, 1H NMR, risible spectra and W(Ⅴ) determination. The photochromism is found mainly to be related to the decatungstate W10O324-, the ligands coordinated with metal ions and the solvents used.

Key words: decatungstate, coordinated compound, DMF, DMSO, photochromism, tungsten(Ⅴ)
