对苯醌二亚胺与对苯乙炔共聚物的金属配合物催化法合成与表征

摘要

Under the presence of metal complex,poly（N,N′-p-benzoquinone diimine-alt-1,4-diethynyl-2,5-bis（n-alkoxy） benzene（PAn-PPE） was synthesized via cross coupling reaction between the N,N′-dich-loro-p-benzoquinone diimine and 1,4-diethynyl-2,5-bis（n-alkoxy） benzene,which was characterized by FT-IR、1H-NMR、GPC、XRD、UV-Vis、PL and TGA.Results show that UV-Vis maximum absorption wavelength of PAn-PPE in THF and TFA is about 440 nm and 490 nm respectively.The photoluminescence excitation and emission peak are about 450 nm and 475 nm,respectively.The copolymers have good electrochemical activities and thermal stability.%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。
