首次采用固相聚合法在室温条件下制备了聚(3,6-二噻基-哒嗪)[P(DThPD)],聚(1,4-二噻基-苯)[P(DTh-Ph)]和聚(4,7-二噻基-2,1,3-苯并噻二唑)[P(DThB)]。并用红外光谱、紫外-可见光光谱、荧光光谱、电子扫描显微镜、电子透射显微镜、循环伏安(cyclic voltammogram)等测试方法,对聚合物进行表征。结果表明,固相聚合法合成的P(DThPD)和P(DThPh)具有纳米颗粒串连的棒状或环状结构;P(DThPD)分别在336 nm、450nm和580nm(w)处有吸收峰;P(DThPh)分别在325nm和410nm处有吸收峰;P(DThB)分别在460nm、550nm和700nm处有吸收峰。P(DThPh)和P(DThB)分别在488nm和599nm处有较强的荧光。循环伏安测试表明,固相聚合法合成的3种聚合物均具有较好的电化学活性。
The poly (3,6-dithiopyridazine) [P (DThPD)], poly (1,4-dithiyl-benzene) [P )] And poly (4,7-dithianyl-2,1,3-benzothiadiazole) [P (DThB)]. The polymers were characterized by infrared spectroscopy, UV-Vis spectroscopy, fluorescence spectroscopy, scanning electron microscopy, electron transmission microscopy and cyclic voltammogram. The results showed that P (DThPD) and P (DThPh) synthesized by solid state polymerization had rod - like or ring - shaped structure with nano - particles in series. P (DThPD) had absorption peaks at 336 nm, 450 nm and 580 nm P (DThPh) has absorption peaks at 325nm and 410nm, respectively; P (DThB) has absorption peaks at 460nm, 550nm and 700nm respectively. P (DThPh) and P (DThB) have strong fluorescence at 488nm and 599nm, respectively. Cyclic voltammetry tests showed that the three kinds of polymers synthesized by solid state polymerization all had good electrochemical activity.
