联苯胺聚合物薄膜直接电化学沉积到导电基板上的二和三苯胺基烷烃单体的氧化偶联。通过改变烷基连接基团，优化了聚合物的电聚合和电化学性能。聚合物膜在高电位（> 3.3V vs. Li/Li（+））下表现出两个可逆的单电子转移，并且即使在4秒内放电时也保持超过150 mA h g（-1）的放电容量。
Thin films of benzidine polymers were electrochemically deposited directly onto conductive substrates by oxidative coupling of di- and trianilinoalkane monomers. The electropolymerization and electrochemical properties of the polymers were optimized by varying the alkyl linker. Polymer films exhibited two reversible one-electron transfers at high potentials (>3.3 V vs. Li/Li(+)) and maintained discharge capacities in excess of 150 mA h g(-1) even when discharged in under 4 seconds.
