摘要： 对2-芳基苯并噁唑衍生物的光谱及光物理行为进行了研究。结果表明,该系列化合物与常见分子内共轭电荷转移化合物的特性明显不同。分析了存在差异的原因,指出该类化合物的较强的荧光发射能力与其分子中的C=N双键的异构化受阻密切相关。

Abstract: The spectra and photophysics of 2-aryl-benzoxazole derivatives have been studied in this work.The obtained results indicate that the photophysical behavior of these compounds is different evidently from those of usual intramolecular conjugated charge transfer compounds and the cause of these differences are discussed and analyzed.In addition,the results also show that the higher fluorescence quantum yields of these compounds are concerned closely in the twist inhibition of the C＝N double bond in the molecules.

Key words: 2-Aryl-benzoxazole, Intramolecular conjugated charge transfer compound, Fluorescence quantum yield
