WebToward the extension of the light-harvesting region of sensitizers in dye-sensitized solar cells (DSSCs), two ethynyl-linked porphyrin trimers were synthesized and investigated. The zinc–freebase–zinc trimer (Zn–FbA–Zn) showed an absorption maximum at a longer wavelength than the all-zinc trimer (Zn–ZnA–Zn), WebDec 9, 2013 · Each porphyrin unit of the synthesized trimer has two transition dipole moments (B x, B y) in the porphyrin plane. Because of the excitonic coupling between the transition dipole moments along the bonding axis (B x ), the excited state is split, and the transition to the excited state with lower energy is allowed, resulting in the red-shifted …
