中文摘要: 采用溶解聚合法使β-四氟乙烷磺内酯分别与邻苯二胺、二氯-邻苯二胺合锌(Ⅱ)和二氯-邻苯二胺合镉(Ⅱ)开环缩聚,制备出邻苯二胺型和金属配位邻苯二胺型含氟聚酰胺磺酰胺聚合物。通过红外光谱、核磁共振氢谱、电感耦合等离子体发射光谱仪、凝胶渗透色谱等手段,确定其分子链为同时含有酰胺、磺酰胺、氟碳基团、芳环和金属离子的特殊结构;采用紫外-可见分光光度计和荧光分光光度计分析表明:邻苯二胺型含氟聚酰胺磺酰胺具有高荧光量子产率0.65,Cd2+配位后荧光量子产率保持0.65,而络合Zn2+的邻苯二胺型含氟聚酰胺磺酰胺的荧光量子产率降低为0.39,Zn2+对该类聚合物的荧光性能具有选择性。

Abstract:Novel fluorine containing polymers, o phenylenediamine and its metal coordination complexes based fluoropoly(amide sulfonamide)s were synthesized for the first time by solution polycondensation of β hydroxytetrafluoroethanesulfonic acid sultone (TFE sultone) and o phenylenediamine, Zn(o PDA)Cl2 and Cd(o PDA)Cl2. Chemical structures of the obtained F PASAs were characterized by GPC, FT IR，1H NMR and ICP AES in detail. Fluorescence quantum yields were investigated by UV Vis and Fluorospectrophotometer. Results show that these functionalized fluoropolymers possess distinctive structures as well as unique fluorescent properties. o Phenylenediamine based fluoropoly(amide sulfonamide)s show a high fluorescence quantum yield of 0.65, and Cd(o PDA)Cl2 based fluoropoly(amide sulfonamide)s display the same fluorescence quantum yield, while fluorescence quantum yield of Zn(o PDA)Cl2 based ones are decreased to 0.39, which indicate the negative influence of Zn2+ on fluorescence quantum yield
