Fluorescein has several applications owing to its properties, such as high molar absorptivity, high fluorescence quantum yield, high photostability, and wavelengths of absorption and emission in the visible region. The syntheses of fluorescein derivatives between phenol and anhydride derivatives by using NbCl as a Lewis acid is described. The products have high yields and short reaction times are observed. The study of the UV/Vis and fluorescence spectra of these derivatives and their application in dye-sensitized solar cells is also described.
由于荧光素具有诸如高摩尔吸光率、高荧光量子产率、高光稳定性以及在可见光区域的吸收和发射波长等特性，它有多种应用。本文描述了以NbCl作为路易斯酸，在苯酚和酸酐衍生物之间合成荧光素衍生物的过程。产物产率高，且反应时间短。还介绍了对这些衍生物的紫外/可见光谱和荧光光谱的研究及其在染料敏化太阳能电池中的应用。
