3‐hydroxychromone derivatives with high fluorescence quantum yields and molar extinction coefficients. Two of these derivatives (9 and 10 a) have been studied as fluorophores for cellular imaging in HeLa cells and show excellent permeability and promising fluorescence properties in a cellular environment. In addition, we have demonstrated by photophysical characterisation of 3‐isobutyroxychromone derivatives that
我们介绍了具有高荧光量子产率和摩尔消光系数的一系列结构多样的,荧光的2,6,8-三取代的3-羟基色酮衍生物的合成和光物理特性。已经研究了这些衍生物中的两种(9和10a)作为在HeLa细胞中进行细胞成像的荧光团,并在细胞环境中表现出出色的渗透性和有希望的荧光特性。此外,我们通过对3-异丁氧基苯并二氢色酮衍生物的光物理表征证明,对3-羟基进行酯化可以产生可接受和有用的荧光性质。
