Poly(pyridinium phenylene) conjugated polymers are synthesized by a cross-coupling and cyclization sequence. These polyelectrolytes are freely soluble in water and display high degrees of electroactivity. When reduced (n-doped) these materials display in situ conductivities as high as 160 S/cm. The high conductivity is attributed to the planar structure that is enforced by the cyclic structures of the polymer. The electron affinities are compared to PCBM, a C(60) based n-type material. We find that these polymers undergo excited state electron transfer reactions with other donor conjugated polymers and hence may find utility in photovoltaic devices.
聚（吡啶基亚苯）共轭聚合物是通过交叉偶联和环化序列合成的。这些聚电解质在水中具有高溶解度，并具有高度的电活性。当被还原（n 掺杂）时，这些材料的原位电导率高达 160 S/cm。高导电性归因于聚合物的环状结构所强制的平面结构。电子亲合势与基于 C(60)的 n 型材料 PCBM 进行了比较。我们发现这些聚合物与其他供体共轭聚合物发生了激发态电子转移反应，因此可能在光伏器件中有应用。
