Efficient synthesis of 2,5-diaryl substituted 4-azido-1,2,3-triazoles by the reaction of sodium azide with dichlorosubstituted diazadienes was demonstrated. The optical properties of the prepared azidotriazoles were studied to reveal a luminescence maximum in the 360–420 nm region. To improve the luminescence quantum yields a family of 4-azido-1,2,3-triazoles bearing ortho-propargyloxy substituents in the
证明了通过叠氮化钠与二氯取代的二氮杂二烯反应有效合成 2,5-二芳基取代的 4-叠氮基-1,2,3-三唑。研究了制备的叠氮三唑的光学性质,以揭示 360-420 nm 区域的发光最大值。为了提高发光量子产率,制备了在 5 位带有邻炔氧基取代基的 4-叠氮基-1,2,3-三唑族。随后的分子内热环化允许构建额外的三唑片段并获得与两个三唑环稠合的独特苯并恶唑辛衍生物。这个新的稠合杂环族具有扁平的杂环系统结构,以提供更多的 5-芳基片段与三唑核的共轭。因此,
