以含有芴结构的芳香二胺单体3,6-二氨基-9-芴酮和不同结构的二溴化合物为底物,通过钯催化C-N交叉偶联缩聚反应合成了三种新型具有芴酮官能团的聚芳亚胺（PIKF）。其数均分子量（-Mn）在3400-4300之间,重均分子量（-Mw）在10200-13800之间,分散系数（-Mw/-Mn）为3.00-3.34。由TG和DSC测定了PIKF的耐热性能,该聚合物具有良好的耐热稳定性（Tg≥200℃,Td〉500℃）。通过对PIKF的光学特性测定表明该聚合物具有良好光学性能,其UV-Vis最大吸收波长为455nm和600nm;最大荧光发射波长因PIKF结构的不同而不同,主要是由于不同聚合物主链结构π电子离域不同。
3,6-dianilino-9-fluorenone and different aromatic dibromides as the monomers, three new fluorine-polyimine（PIKF） have been synthesized via palladium-catalyzed polycondensation reaction.The M-n values are in the range of 3400～4300 and M-w values are in the range of 10200～13800.The polydispersity indexex（PDI） vary from 3.00 to 3.34.The thermal properties of PIKF were detected by thermal behavior（TG） and differential scanning calorimetry（DSC）,and the polymers synthesized show good thermo properties（Tg≥200 ℃,Td500 ℃）.The optical properties of PIKF show that the maximal UV-Vis absorption wavelength is 455 nm and 600 nm,and the maximal fluorescence wavelength is different,which is caused by the different structures of PIKF.
