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103.

Abstract:

Two novel poly(triphenylamine) containing functional quaternary ammonium salt(PTP3FQ 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 by 1H nuclear magnetic resonance(1H NMR), Fourier transform infrared(FTIR), thermogravimetry analysis(TGA) and cyclic voltammogram. PTP3FQ and PP3FQ not only showed good electrochromic properties withoutadding any electrolyte but also exhibited non-volatile memory performance with a large ON/OFF ratio over 103 due to the charge transfer between donor triphenylamine and acceptor oxadiazole.

Key words: Triphenylamine polymer, Functional quaternary ammonium salt, Electrochromism, Non-volatile memory
