摘要: 本工作合成了三种具有不同取代基的二(苯乙烯基)吡嗪类化合物,对它们在不同极性溶剂中的光物理及发光行为进行了研究,对带推电子基的二种含氮芪类化合物(Ⅰ),(Ⅱ)所以具有较强荧光发光行为以及对带硝基的该类化合物(Ⅲ)仅有很弱的萤光发光提出了看法,认为化合物(Ⅰ),(Ⅱ)存在着很弱的邻近效应和化合物(Ⅲ)因硝基的引入大大地促进了不同态间的邻近相互作用是导至本工作结果的主要原因。

Abstract: Three Kinds of substituted distyryl pyrazine derivatives were synthesized and characterized in this work.Their photophysical behavior and emission properties were studied.The causes of the strong emission for the aza-stilbene I,II with electron donating substittients and the weak emission for the compound Ⅲ with nitro-group were also discussed.It was considered that the weak proximity effect of compound Ⅲ was enhanced by the introduction of nitro-group which is the main reason bring about the results obtained in this paper.

Key words: pyrazine, photophysics, proximity effect, isomerization
