以四(三苯基磷)钯(Pd(PPh3)4)和CuI作为催化剂,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3,6-双(5′-溴-2′-噻吩)-哒嗪(TPD)以不同配料比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,共聚物在THF溶液中的荧光量子效率为51%～61%;随着共聚物中TPD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红移。聚合物薄膜的最大发射峰位于540～551nm。
Using tetrakis (triphenylphosphine) palladium (Pd (PPh3) 4) and CuI as catalyst in a solution of diisopropylamine and tetrahydrofuran, a broad band of 1,4-diethynyl-2,5-di A series of novel polyarylalkanes were synthesized at different formulation ratios by using the narrow bands of 3,6-bis (5’-bromo-2’-thiophene) -pyridazine (TPD) The presence of long-chain alkoxy groups makes these polymers have good solubility and film-forming properties in common organic solvents. The UV-Vis absorption, fluorescence emission and cyclic voltammetry of the above polymers were investigated. The fluorescence quantum efficiency of the copolymer in THF solution was 51% -61%. With the increase of TPD content in the copolymer, , The initial absorption wavelength of the copolymer film and fluorescence emission wavelength redshift. The maximum emission peak of the polymer film is 540 ~ 551nm.
