Two 3-D and one 2-D metal–organic frameworks [Cu8I8(L1)4]n (1), [Cu8I8(L2)4]n (2) and [Cu4I4(L3)2]n (3) were synthesized using three novel pyridine and pyrazole supported 1,2,3-triazoles, 1-(4-picolyl)-4-butyl-1H-1,2,3-triazole (L1), 1-(4-picolyl)-4-pentyl-1H-1,2,3-triazole (L2) and 1-(4-picolyl)-4-(3,5-dimethylpyrazolylmethyl)-1H-1,2,3-triazole (L3). In both complexes 1 and 2, there co-exist a 1-D Cu(I) oligomer and Cu4 tetrahedron cluster in the 3-D polymeric structures. Complex 3 shows a 2-D (4, 4) net with the stair-step Cu4I4 as node and L3 as a building block. All three complexes exhibit photoluminescence.
合成了两种3D和一种2D金属有机框架[Cu8I8(L1)4]n (1)、[Cu8I8(L2)4]n (2)和[Cu4I4(L3)2]n (3),使用了三种新型吡啶和肼基支持的1,2,3-三唑,分别为1-(4-皮考基)-4-丁基-1H-1,2,3-三唑(L1)、1-(4-皮考基)-4-戊基-1H-1,2,3-三唑(L2)和1-(4-皮考基)-4-(3,5-二甲基肼基甲基)-1H-1,2,3-三唑(L3)。在复合物1和2中,3D聚合物结构中共存着1D Cu(I)寡聚体和Cu4四面体簇。复合物3显示出一个2D (4, 4) 网格,以阶梯状的Cu4I4作为节点,L3作为构建单元。所有三种复合物均表现出光致发光特性。
