title: Synthesis, crystal structure and photoelectric property of two new coordination polymers constructed by longer-spanning suberic acid and 4,4'-bipyridine ligands.
abstract: Two-dimensional coordination polymers, [M(C₈H₁₂O₄)(C₁₀H₈N₂)]·H₂O [M=Co (1), Cd (2); C₁₀H₈N₂ = 4,4-bipyridine, C₈H₁₄O₄=subaric acid] were obtained from the reaction of the metal salts, bipy and subaric acid at 180°C and characterized by elemental analysis, infrared spectrum, and single-crystal X-ray diffraction and surface photovoltage spectrum (SPS). The single-crystal X-ray diffraction showed that the subaric ligand in the two complexes exhibits two types of modes coordinating to transition metal ions, resulting in the formation of a 1D infinite chain along the c-axis. In addition, the results of SPS for complexes 1 and 2 indicate that these two complexes exhibit positive surface photovoltage responses in the range of 300-800 nm, which can be assigned to LMCT and MLCT, respectively. And the SPS of complex 1 also can be assigned to the d→d* electronic transition. The SPS spectra of the two complexes are consistent with their UV-vis spectra.
