Reaction of [Et4N][TpWS3] (1) with [Cu(MeCN)4]PF6, CsCl, isonicotinic acid and CuCN, and treatment of [Et4N][TpWS3(CuCl)3] (2)/[Et4N][{TpWS3Cu3Cl}2(μ-Cl)2(μ4-Cl)] (3) with AgOTf and bpp (Tp = hydridotris(3,5-dimethylpyrazol-1-yl)borate; bpp = 1,3-di(4-pyridyl)propane) give rise to [Et4N]2[{TpWS3Cu3(CN)0.5}2(μ-Cl)2(μ4-Cl)]2(PF6)2 (4) and [(TpWS3Cu3)2(μ3-Cl)2(bpp)3]2(OTf)4 (5), respectively. Compounds 4 and 5 feature cluster-based rectangle and [2]catenane architecture, and both exhibit enhanced third-order nonlinear optical responses relative to those of 1.
[Et4N][TpWS3]（1）与[Cu(MeCN)4]PF6、CsCl、异烟酸和CuCN反应，以及用AgOTf和bpp处理[Et4N][TpWS3(CuCl)3]（2）/[Et4N][{TpWS3Cu3Cl}2(μ-Cl)2(μ4-Cl)]（3）（Tp = 氢三（3,5 - 二甲基吡唑 - 1 - 基）硼酸酯；bpp = 1,3 - 二（4 - 吡啶基）丙烷）分别得到[Et4N]2[{TpWS3Cu3(CN)0.5}2(μ-Cl)2(μ4-Cl)]2(PF6)2（4）和[(TpWS3Cu3)2(μ3-Cl)2(bpp)3]2(OTf)4（5）。化合物4和5具有基于簇的矩形和[2]连环烷结构，并且相对于1而言，两者均表现出增强的三阶非线性光学响应。
