中文摘要: 利用Stille 耦合反应合成了新型单体5，8-二呋喃基萘基喹喔啉，溴化后与不同长链烷氧基侧链的对苯撑乙炔共聚，合成了聚［2，5-二(辛氧基) 1，4-苯撑乙炔撑-5，8-二(呋喃基)萘基喹喔啉(PⅠ)和聚［2，5-二(十二烷氧基)-1，4-苯撑乙炔撑-5，8-二(呋喃基)萘基喹喔啉(PⅡ)。通过FT-IR、1H-NMR等手段对单体和共聚物的结构进行了表征，采用紫外-可见吸收光谱、荧光发射光谱和循环伏安法对聚合物的光、电性能进行了探讨。结果表明：单体和共聚物PⅠ、PⅡ在长波处的紫外-可见吸收峰分别为435、418、423 nm，相应的荧光发射峰分别为551、589、579 nm。2种共聚物均在1.54 V处出现氧化峰，无相应的还原峰。
Abstract:A new monomer 5,8 bis(furanyl) acenaphthenequinoxaline was synthesized by Stille cross coupling reaction and brominated. Its alternating coplymers of poly(2,5 dioctyloxy 1,4 diethynyl phenylene alt 5,8 bisfuranyl acenaphthenequinox) (PⅠ) and poly(2,5 didodecyloxy 1,4 diethynyl phenylene alt 5,8 bisfuranyl acenaphthenequinox) (PⅡ) were prepared with 2,5 dialkoxy 1,4 diethynylbenzene. Both monomers and copolymers were characterized by FT IR, 1H NMR. UV Vis、PL spectra and cyclic voltammetry were used to investigate their optical and electrochemical properties. Results show that monomer and copolymers of PⅠ and PⅡ maximum absorbancs of longer wavelength appear at 435、418、423 nm, corresponding emission peaks at 551、589、579 nm, respectively. The copolymers have maximum oxidation peaks of 1.54 V at the same potential, and exhibit irreversible electrochemical activities.
