Synthesis, crystal structure and photoelectric property of two novel coordinated complexes constructed by 4,4'-bipyridine and sebacic acid

摘要

Two two-dimensional (2D) new complexes: [M(bpy)(C_(10)H_(16)O4)H2O] [M = Ni (1), Co (2); bpy = 4,4-bipyr-idine, C_(10)H_(18)O4 = sebacic acid] were synthesized by the hydrothermal reaction at 180 °C and characterized by elemental analysis, infrared spectra, and thermogravimetric spectra, single-crystal X-ray diffraction and surface photovoltage spectrum (SPS). The single-crystal X-ray diffraction showed that both complexes are isomorphous, crystallized in monoclinic system, and space group P2_(1/c). In addition, The results of SPS for complexes (1) and (2) indicate that these two complexes exhibit positive surface photovoltage response in the range of 300-800 nm, which can be assigned to LMCT and d -> d* electronic transition. The SPS spectra of the two complexes are consistent with their UV-Vis spectra.
