Four water‐soluble 2‐hydroxy‐Nile Blue derivatives, 1 a, 1 b, 2 a, and 2 b, were prepared by condensation reactions performed under relatively mild conditions (90 °C, N,N‐dimethylformamide with no added acid). These fluorescent probes had more favorable fluorescence characteristics than two known water‐soluble Nile Blue derivatives. Specifically, they were superior to the known dyes with respect to
通过在相对温和的条件下(90°C,N,N-二甲基甲酰胺不加酸)进行缩合反应,制备了四种水溶性2-羟基尼罗蓝衍生物1a,1b,2a和2b。。这些荧光探针比两种已知的水溶性尼罗蓝衍生物具有更好的荧光特性。具体而言,它们在水性介质中的量子产率和荧光发射的清晰度方面优于已知染料。浓度依赖性的紫外吸收和荧光发射的研究表明,染料没有聚集在在低于1-4浓度μ水溶液中号。新的水溶性物质1,图1b,2,和图2b中的荧光光谱的一个希望的区域EMIT(λ = 670-675纳米)。总体而言,它们对于在水性环境中标记生物分子具有潜在的意义。
