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、1 H-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、423nm,相应的荧光发射峰分别为551、589、579nm。2种共聚物均在1.54V处出现氧化峰,无相应的还原峰。A new monomer 5,8-bis（furanyl）-acenaphthenequinoxaline was synthesized by Stille cross cou- pling reaction and brominated. Its alternating coplymers of poly（2,5-dioctyloxy-1,4-diethynyl-phenylene- aZt-5,8-bisfuranyl acenaphthenequinox） （P I ） and poly （2,5-didodecyloxy-1,4-diethynyl-phenylene-alt-5, 8-bisfuranyl acenaphthenequinox） （P Ⅱ ） 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 voltam- metry were used to investigate their optical and electrochemical properties. Results show that monomer and copolymers of PI and PⅠ] maximum absorbancs of longer wavelength appear at 435.418.423 nm, cor- responding 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.
