镧系元素-N ,N-二(2-氧吡咯-1-甲基)甘氨酸-邻菲咯啉三元体系的光致变色

Photochromism of the Ternary System Lanthanide- N,N-Bis (2-Oxopyrrolidin-1 -ylmethyl)Glycine Phenanthroline

采用激发光谱、荧光光谱和紫外 可见光谱研究了镧系元素 N ,N 二 (2 氧吡咯 1 甲基 )甘氨酸 (MPG) 邻菲咯啉 (phen)三元体系的性质。研究了该体系水溶液的光致变色。太阳光或汞灯照射下溶液由黄色转变成绿色 ,而在避光处保存 ,绿色褪去变成黄色溶液。

The ternary system Lanthanide (Ln) N,N bis(2 oxopyrrolidin 1 ylmethyl)glycine (MPG) phenanthroline (phen) has photochromism turning from yellow to green in aqueous solution when irradiated with sunlight or Hg lamp while undergoing a reversible colour change from green to yellow in dark. With excitation spectrum, emission spectrum and UV VIS spectra, its photochromic behavior and the effect of pH on it were investigated.
