【摘要】 通过氯甲基化聚砜（CMPSF）与4-羟基水杨醛（HSA）的亲核取代反应,将水杨醛（SA）基团键合在聚砜侧链,制得改性聚砜PSF-SA;再经PSF-SA的醛基分别与苯胺（AN）和环己胺（CA）发生席夫碱反应,获得了两种侧链键合了水杨醛型双齿席夫碱配基的功能化聚砜PSF-SAN和PSF-SCA,产物的结构由红外光谱和核磁共振氢谱表征。以两种功能化聚砜为大分子配体,与Tb（Ⅲ）离子及Eu（Ⅲ）离子分别配位,制得了二元高分子-稀土配合物,初步探索了配合物的光致发光性能。本文重点研究了功能化聚砜PSF-SAN和PSFSCA的制备反应,考察与分析了主要因素对CMPSF与HSA之间亲核取代反应的影响规律。结果表明,对于该亲核取代反应,适宜的溶剂为极性较强的N,N-二甲基乙酰胺,80℃为适宜的反应温度。大分子配体PSFSAN对Eu（Ⅲ）离子的荧光发射产生强烈的敏化作用,配合物PSF-（SAN）₃-Eu（Ⅲ）发射红光;大分子配体PSF-SCA对Tb（Ⅲ）离子的荧光发射也产生敏化作用,配合物PSF-（SCA）₃-Tb（Ⅲ）发射绿光。更多还原

【Abstract】 Two bidentate Schiff base ligand-functionalized PSFs,PSF-SAN and PSF-SCA were synthesized by the substitution reaction under optimal conditions,i. e. in N,N-dimethylacetamide at 80 ℃ from chloromethylated polysulfone（ CMPSF） as starting material and the Schiff base reaction in turn. The chemical structures of products were characterized by FT IR and 1 H NMR techniques. Their binary polymer-rare earth（Tb（ Ⅲ） ion and Eu（ Ⅲ））ion complexes were prepared,and their photoluminescence properties were preliminarily explored. The PSF-SAN produces strong sensitization action towards Eu（ Ⅲ） ion, and the complex PSF-（SAN）₃-Eu（ Ⅲ） emits red fluorescence. While the PSF-SCA produce sensitization action towards Tb（ Ⅲ） ion,and the complex PSF-（SCN）₃-Tb（ Ⅲ） emits green fluorescence.更多还原
