We report on synthesis and photophysical properties of a new class of fluorescent dyes. They are characterized by large Stokes-shifts, long fluorescence lifetimes in organic solvents and a pronounced dependency of the fluorescence lifetime on the solvent polarity. Also worthy of note is the high bleaching stability. To provide access to biochemical and medical applications a series of derivatives were
我们报告了新型荧光染料的合成和光物理性质。它们的特征在于大的斯托克斯位移,在有机溶剂中的长荧光寿命以及荧光寿命对溶剂极性的显着依赖性。还值得注意的是高的漂白稳定性。为了提供进入生物化学和医学应用的途径,制备了一系列衍生物,其对不同的生物学相关官能团(羧酸,胺,马来酰亚胺,N-羟基琥珀酰亚胺酯)表现出特定的反应性。此外,制备了两个炔烃,可用于“点击”化学。
