The planar structure, attractive photophysical property, and scarcity of electronically conjugated fluorene-containing biomolecular building blocks have attracted recent research interest on synthesizing triazolylfluorene decorated nucleosides with modulated photophysical features. Herein, we report the synthesis of few fluorescent nucleosides wherein the C5 of 2′-deoxyuridine is electronically conjugated
电子共轭含芴生物分子构建块的平面结构、有吸引力的光物理性质和稀缺性吸引了最近对合成具有调制光物理特性的三唑基芴修饰的核苷的研究兴趣。在此,我们报告了几种荧光核苷的合成,其中 2'-脱氧尿苷的 C5 通过 Sonogashira 交叉偶联和铜催化的点击反应与芴类似物进行电子共轭。对合成核苷的光物理性质的研究表明,合成的核苷中的两个在各种有机溶剂中显示出有趣的双发射特性。双发射芴核苷可能会对用于监测 DNA 微环境的核酸研究产生重大影响。此外,
