| 摘 要： | 以四(三苯基磷)钯(Pd(PPh3)4)和CuI为催化剂,在二异丙胺和四氢呋喃溶液中,采用宽能带的1,4-二乙炔基-2,5-二(十二烷氧基)苯(PE)和窄能带的4,7-双(5′-溴-2′-呋喃)-2,1,3-苯并噻二唑(FBT)合成了一系列新型聚芳炔。长链烷氧基的存在使得此类聚合物在常用的有机溶剂中具有较好的溶解性和成膜性。通过对上述聚合物的紫外-可见吸收、荧光发射及循环伏安等基本性能进行探讨可知,随着共聚物中FBT含量的增加,共聚物薄膜的吸收起始波长及荧光发射波长均有明显的红移。聚合物薄膜的最大发射峰位于600～650 nm,聚合物中的能量能有效地由PE单元转移到FBT单元上。

| Abstract: | A novel class of poly(aryleneethyny1ene) derivatives were synthesized via cross coupling(between) the large band-gap monomer,1,4-diethynyl-2,5-bis(n-dodecyloxy)benzene(PE),and low band-gap monomer,4,7-bis(5-bromo-2-furan)-2,1,3-benzothiadiazole(FBT),in the medium of tetrahydrofuran and diisopropylamine with Pd(PPh_3)_4 and CuI as catallysts.These polymers are soluble in common organic(solvents) and possess good film-formability due to the decoration of flexible alkyloxy chains.The UV-Vis(absorption,) photol... |
