Abstract
Bridge the gap: Rigid π-conjugated bridges such as the ethynyl spacers, are effective for connecting the phthalocyanine π system to the conduction band of TiO 2. A series of zinc phthalocyanine photosensitizers with carboxyethynyl anchoring groups have been synthesized. Solar cells sensitized with the pictured compound exhibit record efficiencies of 5.5% and 6.1% under 100 (1 sun irradiation) and 9.5 mWcm -2, respectively.
