Abstract A novel isolated cluster-based iodocuprate [Cu(1,10-phen)3]2[Cu11I15] (1) was successfully constructed with in situ generated [Cu(1,10-phen)3]2+ cation as the charge balancer and structural directing agent. In compound 1, the linkage of Cu(I) and I- generated an anionic [Cu3I4] building unit, and alternate connection of these moieties with each other further gave rise to a bowknot-like high-nuclearity Cu-I cluster. By virtue of the intermolecular forces, a three-dimensional supramolecule was finally fabricated with the transition metal complex as the template and guest species. A short Cu-Cu distance could be observed, suggesting the existence of closed-shell d10-d10 cuprophilic interaction in the structure of 1. Interestingly, the photocatalysis experiment has been performed on solid 1, which implies that the title compound could be acted as a promising visible light driven photocatalyst for the degradation of the organic dye indigo carmine (IC). In addition, the mechanism for the photodegradation process has been discussed in detail.

构建过渡金属络合物定向碘铜酸盐作为可见光驱动的光催化剂

摘要 以原位生成的 [Cu(1,10-phen)3]2+ 阳离子为电荷, 成功构建了一种新型孤立簇基碘铜酸盐 [Cu(1,10-phen)3]2[Cu11I15] (1)平衡剂和结构导向剂。在化合物 1 中，Cu(I) 和 I- 的连接产生了阴离子 [Cu3I4] 构建单元，这些部分相互交替连接进一步产生了蝴蝶结状的高核 Cu-I 簇。借助分子间作用力，最终以过渡金属配合物为模板和客体制备了三维超分子。可以观察到短的 Cu-Cu 距离，表明在 1 的结构中存在闭壳 d10-d10 亲铜相互作用。有趣的是，光催化实验已在固体 1 上进行，这意味着标题化合物可以作为一种有前途的可见光驱动光催化剂，用于降解有机染料靛蓝胭脂红（IC）。此外，还详细讨论了光降解过程的机制。
