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。
Using tetrakis (triphenylphosphine) palladium (Pd (PPh3) 4) and CuI as catalyst in a solution of diisopropylamine and tetrahydrofuran, a wide band of 1,4-diethynyl-2,5-di A series of new types of 4,7-bis (5’-bromo-2’-furan) -2,1,3-benzothiadiazole (FBT) Polyarylene. The presence of long-chain alkoxy groups makes these polymers have good solubility and film-forming properties in common organic solvents. Through the above-mentioned UV-Vis absorption, fluorescence emission and cyclic voltammetry and other basic properties discussed, with the FBT content of the copolymer increases, the copolymer film absorption start wavelength and fluorescence emission wavelength were significant Red shift. The maximum emission peak of the polymer film lies between 600 and 650 nm and the energy in the polymer can be efficiently transferred from the PE unit to the FBT unit.
