摘要: AbstractFilter('ChDivSummary','ChDivSummaryMore','ChDivSummaryReset');采用半固相法合成一水合对苯二酚铜(Ⅱ)和一水合对苯二酚钴(Ⅱ),分别用碘量法和EDTA滴定法测定配合物中铜、钴的含量,通过元素分析、红外光谱、紫外吸收光谱、荧光光谱表征两种配合物的组成.结果表明:采用半固相反应法可以合成一水合对苯二酚铜(Ⅱ)和一水合对苯二酚钴(Ⅱ),在两种配合物的荧光光谱中都出现2个激发峰和1个荧光发射峰,说明过渡金属的对苯二酚配合物可用做潜在的发光材料Abstract: Hhydration hydroquinone copper complex and hydroquinone cobalt complex were synthesized by quasi solidstate method.The content of both complexes were determined by iodimetry and EDTA titration.The composition of both complexes were characterized by elemental analysis, IR, ultraviolet absorption spectra and fluorescence spectra. The results indicated that pure hydration hydroquinone copper complex and hydroquinone cobalt complex were obtained.Two excitation peaks and one emission peak appeared in fluorescence spectra of both complexs showed such transition metal hydroquinone complexes can be used as a potential luminescent material.
