a new class of pyrene-based biomolecular probes. The absorption maxima of the alkynylpyrenes were seen to be shifted to longer wavelengths compared with those of the unsubstituted parent pyrene. Fluorescence quantum yields of the alkynylpyrenes dramatically increased up to 0.99 in ethanol, and only slight quenching of the fluorescence occurred even under aerated conditions. The alkynylpyrenes have
为了开发新型的基于-的生物分子探针,已经详细研究了各种炔基py衍生物的光化学性质。与未取代的母体pyr相比,炔基py的吸收最大值移至更长的波长。在乙醇中,炔基吡啶的荧光量子产率急剧增加至0.99,即使在充气条件下,荧光也只有轻微的猝灭。炔基吡啶已经成功地引入到代表性的生物分子中,例如肽,蛋白质和DNA。标记的生物分子的可检测性得到了显着提高,同时保持了the核的独特光化学特性。
