Visible-light-driven photocatalysis is a promising approach for the degradation of organic pollutants due to its effective utilization of sunlight resources. Therefore, the design and synthesis of novel coordination polymers (CPs) as photocatalysts and the regulation of photocatalytic performance have attracted considerable attention. Herein, we designed and synthesized a light absorption ligand 1-(carboxymethyl)-1H-pyrazole-4-carboxylic acid (H 2 cmpc) and prepared six novel CPs with different 3d transition metal ions, named [Mn 3 (cmpc) Co (2), Ni (3), Co 0.4 Ni 0.6 (4)), and [M(Hcmpc) 2 (H 2 O) 4 ] (M = Co (5), Ni (6)). The H 2 cmpc organic linker has three kinds of coordination bridging modes in the six CPs. CP 1 presents a layered structure with a channel. CPs 2−4 are isostructural and show a onedimensional chain structure. CPs 5 and 6 are isostructural and exhibit a mononuclear structure with six-coordinated metal ions, which are connected into a 3D supramolecular structure constructed through hydrogen bonds. Photocatalytic degradation experiments of CPs 2−4 were conducted, indicating that CPs 2−4 show excellent photocatalytic performance under visible light. Furthermore, Co/Ni codoping can enhance the photocatalytic performance compared with single metal CPs. The photocatalytic degradation mechanisms of CPs 2−4 have been investigated.

“…In order to realize efficient emission for the purposes of environmental application, a potential strategy is to introduce a suitable organic ligand that can shield Ln 3+ cations from water molecules and allow them to emit their characteristic luminescence via the so-called "antenna effect". [25][26][27][28][29][30][31][32] Therefore, we designed a new π-conjugated N-heteroaromatic organic linker (Scheme 1), namely 3-(carboxymethoxy)-1-(carboxymethyl)-pyrazole-4-carboxylic acid (H 3 ccpc), for further synthesis of Ln-CPs. This ligand linker is characteristic of many forms of chelating coordination donors for lanthanide cations, which are favorable for shielding lanthanide cations from solvent molecules.…”

“…The relevant research of CPs with similar polycarboxylic acids based on pyrazole has confirmed the above viewpoint. [29][30][31][32][33][34][35][36][37][38][39] Based on the above consideration, we designed and synthesized a novel pyrazole carboxylic acid compound (H 3 ccpc). It was employed as an organic ligand to self-assemble with Ln 3+ ions, and a novel Ln-CP was successfully obtained, namely, {[Tb 2 (ccpc) 2 (H 2 O) 6 ]•1.5H 2 O} n (ccpcTb).…”
