    Synthesis and Fluorescent Properties of o Phenylenediamine and Its Metal CoordinationComplexes Based Fluoropoly(amide sulfonamide) s

    • 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
