Abstract
Under solvothermal conditions a new coordination polymer, [Ag(L)0.5]n (1) (H2L = azobenzene-4,4′-dicarboxylate), has been obtained successfully. Complex 1 has a three-dimensional (3D) framework structure with (3,6)-connected {4.62}2{42.610.83} topology. The co-sensitization of complex 1 and Ru-bipyridine dye (N719) increases the absorption of the dye-sensitized solar cells (DSSCs) in the ultraviolet region. When the illumination intensity is 100 mW cm−2, the photoelectric conversion efficiency of DSSC (complex 1/N719/TiO2) can reach to 3.14%. The result shows that the DSSC (complex 1/N719/TiO2) possessed excellent photovoltaic performance. Moreover, fluorescent property was also investigated.
