The conjugated polyelectrolytes, which are defined as an ionic conjugated polymer with a significant fraction of covalently attached ionic groups, are of great interests because these materials show ionic and electrical conductivities in a flexible solid network. The synthesis of various ionic polyacetylenes with pyridyl substituents having the designed counter ions have been performed by the in-situ polymerization of ethynylpyridine using the functional reactants without any additional catalysts in relatively high yields. Here, we prepared the conjugated polymers with pyridinium salts and characterizaed the polymer structure. Quasi-solid-state DSSCs with a SnO2:F/TiO2/D719 dye/solid-state electrolyte/Pt device was fabricated with conjugated polymers with pyridinium moieties, which showed the power conversion efficiency (PCE) of 5.33-6.01%. |
