In this work graphene oxide was covalently modified by ruthenium trisbipyridine through non-conjugative and conjugative bridges respectively. The obtained ruthenium trisbipyridine-graphene oxide (Ru (Ⅱ)-GO) nanocomposites were characterized by IR, UV-Vis, energy dispersive X-ray spectrum (EDS), TEM and XRD in detail. Especially, their photovoltaic properties were detected by photocurrent response measurements. Under visible light irradiation, the Ru (Ⅱ)-GO with conjugative bridge exhibited a large photocurrent density of 3.5 μA/cm², which was 3.3 times as that of the Ru (Ⅱ)-GO with non-conjugative bridge, indicating that the bridge structures have significant influence on the photovoltaic properties of Ru (Ⅱ)-GO nanocomposites.
