Two novel hybrid materials based on two kinds of octamolybdate anions and metalâorganic frameworks (MOFs), namely, [Ag8(L1)4(α-Mo8O26)(β-Mo8O26)(H2O)3]·H2O (1) and [CuI3.1CuII0.5(β-Mo8O26)0.5(ζ-Mo7VIMoVO26)0.5(L2)2(H0.8L2)0.5] (2), where L1 = 1,1â²-(1,3-propanediyl)bis[2-(4-pyridyl)benzimidazole] and L2 = 1,1â²-(1,4-butanediyl)bis[2-(3-pyridyl)benzimidazole], have been successfully synthesized. Crystal structure analysis revealed that 1 is a three-dimensional (3D) framework constructed of silver(I)âorganic sheets and two types of (Mo8O26)4â isomers. Compound 2 is a rare 3D framework containing copper(I,II)âorganic cages and 1D channels occupied by the (ζ-Mo7VIMoVO26)5â and (β-Mo8O26)4â anions. The two compounds were characterized by elemental analysis, IR spectroscopy, diffuse reflectivity spectroscopy, and photoluminescent spectroscopy. In addition, the photocatalytic behavior of 1 was investigated.
两种基于八钼酸阴离子和金属有机框架(MOFs)的新型杂化材料,即[Ag8(L1)4(δ-Mo8O26)(δ-Mo8O26)(H2O)3]Â-H2O (1)和[CuI3.1CuII0.5(δ-Mo8O26)0.5(δ-Mo7VIMoVO26)0.5(L2)2(H0.8L2)0.5](2),其中 L1 = 1,1â²-(1,3-丙二基)双[2-(4-吡啶基)苯并咪唑]和 L2 = 1,1â²-(1,4-丁二基)双[2-(3-吡啶基)苯并咪唑]。晶体结构分析表明,化合物 1 是由银(I)无机片和两种 (Mo8O26)4â 异构体构成的三维框架。化合物2是一种罕见的三维框架,包含铜(I,II)无机笼和被(¶-Mo7VIMoVO26)5â和(δ-Mo8O26)4â阴离子占据的一维通道。通过元素分析、红外光谱、漫反射光谱和光致发光光谱对这两种化合物进行了表征。此外,还研究了 1 的光催化行为。
