efficient molecular editing protocols. The examination of the fluorescent properties and further structural optimization of these compounds afforded three new pyrrolocoumarin dyes with notably large Stokes shifts and satisfactory fluorescent properties. Among these, 30 showed a large Stokes shift (113 nm) and intense fluorescence (φ = 0.55, λem = 523 nm), and thus showed great potential in biological imaging
具有大斯托克斯位移和长发射波长的小型有机荧光分子是各种现代荧光成像技术(如 FRET)的理想染料。在这项研究中,我们在两个吡咯香豆素骨架的基本结构上设计并合成了许多新的荧光分子,其中 Fischer 的吲哚合成和 Suzuki 偶联成功地作为有效的分子编辑方案。对这些化合物的荧光特性和进一步结构优化的检查提供了三种具有显着大斯托克斯位移和令人满意的荧光特性的新型吡咯并香豆素染料。其中,30 表现出较大的斯托克斯位移(113 nm)和强烈的荧光(φ = 0.55,λem = 523 nm),因此在生物成像研究中显示出巨大的潜力。(© Wiley-VCH Verlag GmbH & Co.
