tetrahydroquinoxaline donor into boron difluoride complexes largely extended their emissions (617-684 nm), highly improved their fluorescence quantum yields (up to 0.68) and greatly increased their Stokes shifts (up to 209 nm). These new fluorescent dyes showed reversible ratiometric solid-state fluorescence changes upon switched acid/base fumings. Significantly, these boron difluoride complexes were successfully
在四氟化硼络合物中引入四氢喹喔啉供体大大扩展了它们的发射(617-684 nm),极大地提高了其荧光量子产率(高达0.68),并大大提高了它们的斯托克斯频移(高达209 nm)。这些新的荧光染料在切换酸/碱发烟后显示出可逆的比例固态荧光变化。重要的是,这些二氟化硼配合物已成功地用作活细胞和斑马鱼的显像剂。
