discovery of a powerful novel fluorophore class with an imidazo[1,2-a]pyridinium core, termed PyrAtes. The synthesis was achieved in a single step, demonstrating a wide array of substrates with Stokes shifts as large as 240 nm, while also reaching NIR−I emissions at λmax up to 720 nm. These novel fluorophores were successfully applied in live cell imaging in HEK293 cells, suggesting PyrAtes as potent intracellular
我们在这里报告了一种强大的新型荧光团类别的发现,该荧光团具有咪唑[1,2-a]吡啶核心,称为 PyrAtes。合成是一步完成的,展示了斯托克斯位移高达 240 nm 的各种底物,同时还达到了 λmax 高达 720 nm 的 NIR−I 发射。这些新型荧光团成功应用于 HEK293 细胞的活细胞成像,表明 PyrAtes 是有效的细胞内标志物。
