AbstractThe synthesis, characterization and optical spectroscopy of a deep blue platinum(II) polyyne functionalized with the (3,4-ethylenedioxythiophene)-benzothiadiazole hybrid spacer (P1) and its dinuclear platinum molecular model complex (M1) are described. This metalated polymer P1 exhibits good thermal stability and possesses a narrow bandgap of 1.76 eV. Optical spectroscopic measurements of these materials reveal a substantial donor-acceptor interaction along the rigid backbone of the organometallic polyynes through the interaction of metal center and the conjugated tricyclic ligand. Preliminary study shows that P1: methanofullerene acceptor blend can be used as an active layer of bulk-heterojunction polymer solar cells. Photoexcitation of this blend layer in some yet-to-be optimized cells results in a photo-induced electron transfer from the π-conjugated metallopolyyne electron donor to [6,6]-phenyl C 61-butyric acid methyl ester with a power conversion efficiency (PCE) close to 0.30% under air mass (AM1.5) simulated solar illumination. The power dependencies of the solar cell parameters (including the short-circuit current density, open-circuit voltage, fill-factor and PCE) were also studied. © 2008 Elsevier B.V.
