Two novel pyridyl and thioether hybridised 1,2,3-triazole ligands 1-(2-picolyl)-4-(2-(methylthio)-pyridine)-1H-1,2,3-triazole (L1) and 1-(4-picolyl)-4-(2-(methylthio)-pyridine)-1H-1,2,3-triazole (L2) were prepared from CuAAC click reactions. Reactions of CuI with the ligands L1 and L2 yielded two one-dimensional coordination polymers [Cu6I6(L1)2]n (1) and [Cu2I2(L2)2]n (2). Single-crystal X-ray diffraction reveals that 1 and 2 are polymeric with [Cu6I6] and [Cu2I2] respectively as building blocks. Both ligands (L1 and L2) and complexes (1 and 2) are photoluminescence active. Complexes 1 and 2 are also catalytically active towards azide-alkyne cycloaddition reactions.
两种新型吡啶基和硫醚杂化 1,2,3-三唑配体 1-(2-吡啶基)-4-(2-(甲硫基)-吡啶基)-1H-1,2,3-三唑 (L1) 和 1-(4-吡啶基)-4-(2-(甲硫基)-吡啶基)-1H-1,2,3-三唑 (L2) 是通过 CuAAC 点击反应制备的。CuI 与配体 L1 和 L2 的反应生成了两种一维配位聚合物 [Cu6I6(L1)2]n (1) 和 [Cu2I2(L2)2]n (2)。单晶 X 射线衍射表明，1 和 2 分别以 [Cu6I6] 和 [Cu2I2] 为构筑单元形成聚合物。两种配体 (L1 和 L2) 和配合物 (1 和 2) 都具有光致发光活性。配合物 1 和 2 对叠氮化物-炔烃环加成反应也具有催化活性。
