在金属配合物的存在下,通过N,N′-二氯对苯醌二亚胺与1,4-二炔基-2,5-二(烷氧基)苯共聚,得到了一系列新型交替共聚物聚[N,N′-对苯醌二亚胺-1,4-二炔基-2,5-二(烷氧基)苯](PAn-PPE)。采用FT-IR、1H-NMR、GPC、XRD、UV-Vis、PL、TGA等测试手段对共聚物的化学结构和性能进行表征。结果表明:在四氢呋喃和三氟乙酸溶液中,此类共聚物的紫外-可见最大吸收波长分别约为440 nm和490 nm;其荧光激发峰为450 nm,相应的发射峰为475 nm;具有良好的电化学活性和热稳定性。
In the presence of a metal complex, a series of new alternations were obtained by the copolymerization of N, N’-dichlorophenquinonediimine with 1,4-diynyl-2,5-di (alkoxy) benzene Copolymer Poly [N, N’-p-quinonediimine-1,4-diynyl-2,5-di (alkoxy) benzene] (PAn-PPE). The chemical structure and properties of the copolymer were characterized by FT-IR, 1H-NMR, GPC, XRD, UV-Vis, PL, TGA and other tests. The results showed that the UV-vis absorption maximum wavelength of these copolymers were about 440 nm and 490 nm respectively in tetrahydrofuran and trifluoroacetic acid solution; the fluorescence excitation peak was 450 nm and the corresponding emission peak was 475 nm; Electrochemical activity and thermal stability.
