A series of poly(arylamine)s formulated as [−(Ar)mNR−]n (Ar = p-phenylene or pyridine-2,5-diyl; m = 2−4; R = H or alkyl) were prepared. Ni- or Pd-promoted dehalogenative polycondensation of the corresponding BOC- (tert-butoxycarbonyl-) substituted dibromo monomers afforded poly(oligo-p-phenylene-amine)s, [−(p-C6H4)mN(BOC)−]n (m = 2−4). Deprotection of the BOC group of the polymer at 200 °C gave [−(p-C6H4)mNH−]n
制备了一系列配制为[-(Ar)m NR-] n的聚(芳胺)(Ar =对亚苯基或吡啶-2,5-二基;m = 2-4; R = H或烷基)。相应的BOC-(叔丁氧羰基-)取代的二溴单体的Ni-或Pd促进的脱卤缩聚反应提供了聚(低聚对苯撑亚胺)s,[-(p -C 6 H 4)m N(BOC) −] n(m = 2-4)。聚合物的BOC基团在200°C脱保护得到[-(p -C 6 H 4)m NH-] n(m= 2-4)。该聚合物表现为聚(苯胺)PAn和聚(对亚苯基)PPP之间的中间聚合物。例如,[-(p -C 6 H 4)2 NH-] n(P(DPA))在相对于Ag + / Ag的0.3和0.65 V处显示两个氧化峰,其CV(循环伏安法)图中强度相同,类似于PAn ; 相反,[-(p -C 6 H 4)4 NH-] n的CV图在0.60 V处相对于Ag +表现出主氧化峰/ Ag,类似于PPP。碘
