摘要
用3-二甲氨基苯酚与超支化聚芳醚酮(HPETFDEK-F)的末端氟发生反应,制得荧光超支化聚芳醚酮(FHPETFDEK).采用1H NMR,FTIR,DSC和TGA等方法对所得到的聚合物结构和热性能进行了表征.研究了FHPETFDEK的紫外吸收及荧光发射光谱,发现其具有荧光行为.
Hyperbranched poly（ aryl ether ketone）s（HPETFDEK-F） were synthesized from the combination of 3,3＇, 5,5＇, -tetramethyl biphenyl-4,4＇-diol （ A2 ） and B 3, a novel monomer 1,3,5-tris [ 4- （ 4-flourobenzoyl ） phenoxy ] benzene synthesized in our lab. The FHPETFDEK was prepared by an end-capping approach. The chemical structure of such a polymer was confirmed by ^1H NMR, FTIR, DSC and TGA. The UV and fluorescent spectra of FHPETFDEK were studied and fluorescence phenomena were observed.
