Structural insights of a group of bi-1,2,3-triazoles derived from oxidative CuAAC are described through an X-ray crystallography study, distinguishing a dihedral angle which is ranged from 76.45 to 86.39° between the two 1,2,3-triazole rings. In addition, compound 1 containing a phenyl moiety displays a strong blue emission ( λ em = 394 nm); this structure-related photoluminescence is attributed to the rigidity of the molecule and the conjugation between phenyl groups and the triazole fragments.

双1,2,3-三唑的合成、结构分析和光物理性质

通过 X 射线晶体学研究描述了一组源自氧化 CuAAC 的双 1,2,3-三唑的结构见解，区分了两个 1,2,3-之间的二面角，范围为 76.45 到 86.39°。三唑环。此外，含有苯基部分的化合物1显示出强烈的蓝色发射（λ em = 394 nm）；这种结构相关的光致发光归因于分子的刚性以及苯基与三唑片段之间的共轭。
