A novel symmetrical ruthenium complex (Ru-1) bearing pyrene groups was synthesized, and its molecular structure and purity were characterized by 1H-NMR and ESI-MS. The ruthenium complex delivered ideal stability and performance over a wider range of temperature (below 400℃), which suggests that the stability of this material can satisfy the requirement of dye-sensitized solar cell. Thin films of Ru-1 complex can be prepared onto both graphene- and HOPG-electrode surface via self-assembly process, then their surface morphology and photoelectricity property were examined by means of AFM, Cyclic voltammetry and UV-vis spectroscopy. The results show that the growth of the film was uniform. A couple of sensitive and reversible redox peaks were acquired from the cyclic voltammograms of Ru-1 modified carbon electrodes, the Ru (II/III) oxidative peak was observed at 0.47 V. Uv-vis absorption spectra show that the membrane materials have intense and wide absorption peaks in a wider range, which is favorable for capture sunlight at longer wavelength. In sum, a carbon electrode of excellent photoelectric properties and stability can be obtained by modifying both graphene and HOPG electrodes with Ru-1complex. © All right reserved.
