三维超分子银配合物的合成、结构及光催化性能研究

Synthesis, Structures, and Photocatalytic Properties of a Three-dimensional Silver(Ⅰ) Supramolecular Complex

采用水热法合成了一种三维银的超分子配合物[Ag(L)(1,3-HBDC)]n(1)(L=1,4-双(苯并咪唑基)丁烷,1,3-H2BDC=1,3-苯二甲酸)。用物理化学、光谱学等方法对其进行了合成和表征。配合物1为一维链结构,并进一步由1,3-HBDC未配位的羧基和Ag(Ⅰ)中心的Ag…O键作用扩展成3D超分子骨架材料。该配合物在紫外光照射下,对亚甲基蓝的降解表现出了较高的光催化活性。

Using a hydrothermal synthesis method, one silver(Ⅰ) three-dimensional supramolecular complex [Ag(L)(1,3-HBDC)]n(1)(L=1,4-butanediyl)bis-1 H-benzimidazole,1,3-H2BDC=1,3-benzenedicarboxylic acid) was synthesized and characterized by physicochemical and spectroscopic methods. 1 possesses a 1 D infinite chain structure and further extended into a 3D supramolecular framework by 1,3-HBDC anions via Ag…O weak interactions between the uncoordinated carboxylic groups and Ag(Ⅰ) centers. The complex exhibits high photocatalytic activity during photocatalytic degradation of MB under UV irradiation.
