| 摘 要： | 利用荧光光谱技术研究了不同自由基型光引发剂的瞬态及稳态荧光光谱特性,从分子结构出发分析了共轭结构对光引发剂荧光光谱的影响.实验结果表明随共轭效应的增强,荧光激发与发射峰波长逐渐增大;瞬态荧光谱的衰减受电子基团的影响较为明显,含有吸电子基团的光引发剂荧光衰减快,而含有给电子基团的光引发剂荧光衰减慢.通过对溶剂极性及粘度研...

| Abstract: | The fluorescence characteristic of various free radical photoinitiators was investigated by fluorescence spectroscopy.The influence of conjugated structure on fluorescence spectrum was analyzed from the molecular structure.The results show that: the wave length of fluorescence excitation spectrum gradually augments with the conjugative effect enhancement,and so does the peak of fluorescence emission spectrum.The transient fluorescence spectrum of photoinitiator is affected by electron groups and the fluores... |
