Controlling the Rotation of Porphyrin Units in Ethynyl-linked Porphyrin Trimers for Dye-sensitized Solar Cells by Anchoring onto TiO2 Surface
An ethynyl-linked porphyrin trimer bearing carboxyphenyl anchoring groups at all the porphyrin units becomes planar upon adsorption onto TiO2, showing the Q band absorption and IPCE maximum at longer wavelengths.
