摘要:从3-苯并咪唑取代香豆素和不同芳香醛合成了三种具有高量子产率的新型亚氨基香豆素衍生物.通过uv-可见光谱和荧光光谱在极性和非极性溶剂中研究了合成化合物的光物理行为.这些化合物在450Nm左右显示最大吸收峰,在500Nm左右显示最大发射峰.这些化合物在二氯甲烷和氯仿中的量子产率大于0.90.化合物的吸收,发射和量子产率依赖于溶剂极性.除了强烈的吸收外,这些化合物在研究的溶剂中还显示肩峰吸收.溶剂极性图揭示了合成分子中从给体到受体的电荷转移过程.密度泛函理论和含时密度泛函理论计算被用来更好地理解染料的结构,分子,电子和光物理参数.通过ft-Ir,1H NMR,13C NMR和质谱分析对染料进行了表征.

标 题:Preparation of certain m-aminophenols and the use thereof for preparation of laser dyes
发明人：HAMMOND PETER R
权利人:US ENERGY
摘要:Methods are provided for making certain m-aminophenols using a sulfonation/alkali fusion procedure. The aminophenols are key intermediates in the synthesis of dyes, particularly efficient, stable dyes for laser application. Preparations of some rhodamine and phenoxazone dyes from the m-aminophenols are described.
