摘要
首次使用固相法制备出了分子内电荷移动型(CT type)共轭聚合物聚(3,6-二噻基-哒嗪)(P(DThPD)),在25℃测得聚合物的特性黏度为0.67 dL/g。并利用核磁共振谱(1H-NMR)、红外光谱(FT-IR)、紫外-可见光谱(UV-vis)、电子扫描显微镜(SEM)、电子透射显微镜(TEM)、元素分析(elemental analysis)、循环伏安(CV)等测试方法对聚合物进行了表征。结果表明,DThPD在研磨过程中在d,d′位置发生了聚合反应,生成了纳米粒子聚合物,并且聚合物具有一定的电化学活性。
A novel pyridazine derivative 3,6-dithiophenyl-pyridazine has been synthesized by coupling of 3, 6- dibromo-pyridazine and 2-（tributylstannyl）-thiophene via Stille reaction. Poly （3, 6-dithiophenyl-pyridazine）, of which the intrinc viscositic in DMF is 0.67 dL/g at 25 ℃. Charge transfer type（CT type） in molecule conjugated polymer （poly（3,6-dithiophenyl-pyridazine）） was synthesized by one-step solid-state reaction at room temperature. To our knowledge, it＇s the first time to prepare pyridazine-based conjugated polymers using this polymerization method by nowadays. The chemical structure of monomer and polymer was verified by ^1H-NMR, FT-IR and elemental analysis, and the ^1H-NMR and FT-IR. Results show that polymerization is happened at the d, d′-positions of 3, 6-dithiophenyl-pyridazine. The optical, microscopy and electrochemistry properties of polymer were also investigated here. The conjugated polynler is a kind of potential functional,macromolecule material.
