The exploitation of new titanium‐based coordination polymers (Ti CPs) with high crystallinity is difficult but highly desirable for their potential applications in photocatalysis. Herein, a cluster‐cooperative assemble strategy is developed to synthesize Ti CPs. By utilizing various bifunctional ligands containing carboxylate acids and N‐donor groups, we successfully assembled the zero‐dimensional (0D) [(Ti 3 O)( i PrO) 8 ] 2+ or [(Ti 4 O 2 )( i PrO) 6 ] 6+ clusters into one‐dimensional (1D) tube‐, ribbon‐, or helical chain‐shape architectures, two‐dimensional (2D) layered structures, and a rare parallel 2D→three‐dimensional (3D) polycatenation framework with various copper iodide dopants, including rhombus‐ or wing‐shaped Cu 2 I 2 and tetrahedron‐ or ladder‐shaped Cu 4 I 4 . The as‐synthesized compounds display strong absorption in the visible region with narrow band gaps ranging from 1.70 to 2.72 eV and exhibit good photocatalytic activities in the degradation of organic pollutants.
