摘　　要：Two organic sensitizers （LI-33 and LI-34） with double anchoring units were synthesized and utilized for dye sensitized solar cells （DSSCs）, which contained thiophene or vinyl thiophene as n-bridge. The introduction of double anchoring units can change their absorption spectra and energy levels in a large degree, thus, the better light-harvesting ability and the convenient electron transfer along the whole molecule can be obtained. The solar cell based on LI-34 exhibited a broad incident photon- to-current conversion efficiency （IPCE） spectrum and high conversion efficiency （η=6.05%） with coadsorbent CDCA.Two organic sensitizers(LI-33 and LI-34) with double anchoring units were synthesized and utilized for dye sensitized solar cells(DSSCs), which contained thiophene or vinyl thiophene as π-bridge.
