Two n-type conjugated polymers with different backbones and a n-type dopant 1,3-dimethyl-2-(3,4,5-trimethoxyphenyl)-2,3-dihydro-1H-benzo[d]imidazole (TP-DMBI) are synthesized, and electron mobility of 0.53 cm2 V−1 S−1, electrical conductivity of 11 S cm−1 and power factor 32 μW m−1 K−2 for n-type organic thermoelectrics are achieved by TP-DMBI doped films, which out-perform N-DMBI doped films.
两种具有不同主链的 n 型共轭聚合物和一种 n 型掺杂剂 1,3-二甲基-2-(3,4,5-三甲氧基苯基)-2,3-二氢-1 H-苯并[d]咪唑 (TP- DMBI) 被合成,并且通过 TP-DMBI 实现了0.53 cm 2 V -1 S -1 的电子迁移率、11 S cm -1 的电导率和 32 μW m -1 K -2的 n 型有机热电材料的功率因数掺杂薄膜,其性能优于 N-DMBI 掺杂薄膜。
