中文摘要：

通过4-（4-氨基苯氧基）吡啶与4,4＇-二溴二苯醚或1,4-二溴苯的偶合反应（Buchwald-Hartwig）,得到聚[（4-（吡啶-4-氧基）-p-苯氧基]三苯胺或聚[4-（吡啶-4-氧基）]三苯胺,再与3-（氯甲基）-5-[4-（三氟甲基）苯基]-1,2,4-噁二唑进行季铵化反应,得到含功能性季铵盐三苯胺聚合物：聚[N-对苯氧基-N-[4-O-[2-对三氟甲基苯基-（4-氯化吡啶盐）噁二唑]基]三苯胺（PTP3FQ）和聚[N-[4-O-[2-对三氟甲基苯基-（4-氯化吡啶盐）噁二唑]基]三苯胺（PP3FQ）.用核磁氢谱和红外光谱表征了PTP3FQ和PP3FQ的结构,用热失重和循环伏安法测定了PTP3FQ和PP3FQ的热性能和电化学性能.结果表明,在不外加电解质情况下,PTP3FQ和PP3FQ利用自身的季铵盐离子表现出良好的电致变色性能;将PTP3FQ和PP3FQ制成Al/聚合物/ITO结构的记忆器件,由于噁二唑基团与三苯胺形成电荷转移络合物,使记忆器件表现出非易失性可擦写（Flash）存储特性,开关比高达10~3.

英文摘要：

Two novel poly（ triphenylamine） containing functional quaternary ammonium salt（ PTP3 FQ and PP3FQ） were prepared from two dibromo aromatic compounds,bis（ 4-bromophenyl） ether and p-dibromobenzene,and 4-（ 4-aminophenoxy） pyridine via Buchwald-Hartwig coupling reaction,followed by quaterisation reaction with 3-chloromethyl-5-[3-（ trifluoromethyl） phenyl]-1,2,4-oxadiazole. The resulting polymers were characterized by1 H nuclear magnetic resonance（1H NMR）,Fourier transform infrared（ FTIR）,thermogravimetry analysis（ TGA） and cyclic voltammogram. PTP3 FQ and PP3 FQ not only showed good electrochromic properties withoutadding any electrolyte but also exhibited non-volatile memory performance with a large ON / OFF ratio over 10~3 due to the charge transfer between donor triphenylamine and acceptor oxadiazole.
