| Abstract: | Two copper coordination polymers (CPs) Cu(1,2‐BIYB)2(AQ‐2,6‐DA)]n · nH2O ( 1 ) and Cu(1,4‐BIYB)2(AQ‐2,7‐DA)]n · 3nH2O ( 2 ) were obtained by reactions of pentahydrate copper sulfate with corresponding sulfonate and imidazole ligand under hydrothermal conditions, respectively Na2AQ‐2,7‐DA = anthraquinone‐2,7‐disulfonic acid disodium salt, Na2AQ‐2,6‐DA = anthraquinone‐2,6‐disulfonic acid disodium salt, 1,4‐BIYB = 1,4‐bis(imidazol‐1‐ylmethyl)benzene, 1,2‐BIYB = 1,2‐bis(imidazol‐1‐ylmethyl)benzene]. CPs 1 and 2 show different structures: CP 1 has a 2D architecture, which is further extended into a 3D supramolecular structure through hydrogen bonding interactions, whereas CP 2 has a 1D architecture, which generates a 3D supramolecular structure via hydrogen bonding and strong π ··· π interaction. Notably, CPs 1 and 2 feature rare examples of CPs based visible‐light‐driven photocatalysts and reveal good stability toward photocatalysis. |
