Herein are disclosed fluorescent dyes based around a framework for a ligand comprising a pyridyl group linked to a diaryl anilido unit. A variety of ligands based on this framework are disclosed. The ligands chelate to a BF

center to produce the fluorescent dye. The disclosed dyes combine longer Stokes shifts (approximately 100 nm) with increased quantum yields. They are also photostable in aqueous and organic solutions for several hours. These dyes may be used in the labeling of biomolecules for bioimaging and assays. Also disclosed are methods for the synthesis of these dyes.
本文披露了基于含有连接到二芳基苯胺基团的吡啶基团的配体框架的荧光染料。披露了基于这种框架的各种配体。这些配体螯合到BF2中心以产生荧光染料。披露的染料结合了更长的Stokes位移(约100纳米)和增加的量子产率。它们在水溶液和有机溶液中也具有数小时的光稳定性。这些染料可用于生物分子标记用于生物成像和分析。还披露了这些染料的合成方法。
