| 摘要: 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。这种光致变色现象与体系的pH值有关 |

| Abstract: 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 pHon it were investigated. |
| Keywords: photochromism N,N-bis(2-oxopyrrolidin-1-ylmethyl)glycine lanthanides ternary complex |
