摘要: 本工作合成了几种具有强电子给体和不同拉电子能力基团的查耳酮衍生物;对这些化合物的光谱和光物理行为进行了研究,发现该类化合物的发光行为不仅依赖于化合物本身的结构,而且还强烈地依赖于溶剂介质的极性、温度等外部条件,对所得结果进行了扼要的讨论。

Abstract: In this work, several chalcone derivatives which contained strong electron donor moiety and different groups with various electron withdrawing ability were synthesized.The spectra and photophysical properties of these compounds were also studied.Results showed that the luminescence behavior depended on not only the molecular structures, but also the polarity of media used and the enviroment temperature.Results obtained were discussed briefly.

Key words: chalcone, intramolecular charge transfer, photoluminescence, photophy-sical behavior
