Due to the rapid progress of transition metal photocatalysis, developing novel and effective ruthenium photocatalysts and their corresponding heterogeneous counterparts is highly in demand. In this study, we first prepared tetraiodo-substituted 2,6-bis(1,2,3-triazol-4-yl)pyridine ruthenium(II), and further used this complex to construct 2,6-bis(1,2,3-triazol-4-yl)pyridine ruthenium(II) embedded porous organic polymers (POP-Ru). The as-prepared Ru(II) complex was employed as a photocatalyst, which showed higher photocatalytic activity than those of the commercial Ru(II) counterparts, but lower than that of the corresponding polymers. In particular, the polymer POP-Ru-1 has been disclosed to be highly efficient for the photosyntheses of thiocarbomates and disulfides, exhibiting a broad substrate scope. After simple separation workups, the photocatalyst could be recycled and reused for 10 times without obvious loss of its catalytic activity.

2,6-双(1,2,3-三唑-4-基)吡啶钌(II)络合物嵌入多孔有机聚合物作为有机转化的有效光催化剂

由于过渡金属光催化的快速进展，开发新型有效的钌光催化剂及其相应的异相催化剂非常有必要。本研究首先制备了四碘取代的2,6-双(1,2,3-三唑-4-基)吡啶钌( II ),并进一步利用该配合物构建了2,6-双(1,2 ,3-三唑-4-基)吡啶钌( II )嵌入多孔有机聚合物(POP-Ru)。所制备的Ru( II )配合物用作光催化剂，其光催化活性高于商业Ru( II )对应物，但低于相应的聚合物。特别是，聚合物 POP-Ru-1 已被公开对硫代氨基甲酸盐和二硫化物的光合作用非常有效，具有广泛的底物范围。经过简单的分离处理后，光催化剂可以回收再利用10次，催化活性没有明显损失。
