complexes are bridged by pipe ligands to form binuclear clusters. In 2, the MEA ligands link copper(II) complexes to result in an infinite chain structure. Compound 3 contains tetranuclear clusters, which are bridged by Hsa to give an infinite chain structure. Third-order nonlinear optical (NLO) properties of the compounds were determined by Z-scan technique in DMF solution. All three compounds show very
三种铜配合物,[Cu2(Hsa)2(pipe)]·2DMF (1), [Cu(Hsa)(MEA)]n (2), and [Cu4(Hsa)4(DMF)](DMF)} n (3)(管 = 哌嗪;MEA = 甲胺,Hsa =(2-羟基亚苄基)-2-苯氧基乙酰肼),已在室温下在甲醇/DMF 溶液中合成,并通过单晶 X 射线衍射进行结构表征。在 1 中,铜 (II) 配合物通过管道配体桥接形成双核簇。在 2 中,MEA 配体连接铜 (II) 配合物以形成无限链结构。化合物 3 包含四核簇,由 Hsa 桥接形成无限链结构。化合物的三阶非线性光学 (NLO) 特性在 DMF 溶液中通过 Z 扫描技术确定。所有三种化合物都显示出非常强的 NLO 吸收特性,吸收系数 β(MKS),1.71 × 10−10 m W−1 for 1,分别为 1.39 × 10−10 m W−1 和 9.30 × 10−11
