Synthesis of disilanylene polymers with donor-acceptor-type π-conjugated units and applications to dye-sensitized solar cells

► New donor-acceptor type organosilicon polymers were synthesized. ► The polymers were photochemically attached to TiO2 surface, by Si-O-Ti linkages. ► The polymer-attached TiO2 electrodes were applied to dye-sensitized solar cells.
