Abstract In this paper, the polymers containing phenothiazine were synthesized via oxidative polymerization reaction by FeCl3 as oxidant. These polymers contain ether unit, aliphatic chain and aromatic groups as bridges in their structures. The effects of the groups on the optical, thermal, morphological properties of the polymers were investigated. The physical and chemical properties of the monomers and the polymers were identified by FT-IR, NMR, UV–Vis, thermogravimetry (TG), cyclic voltammetry (CV), fluorescence analysis. According to the fluorescence analyses, polymer containing aliphatic ether bridge emitted yellow colour based on the turning of excitation wavelength. The yellow solution of polymer containing aliphatic ether bridge turned into turquoise when excited with the wavelength of 365 nm. Thermal analyses demonstrated that polymer containing phenyl bridge compound had 38% residue amount. Due to fluorescent and thermal properties, these polymers could be used in various applications such as spectrofluorometric ion sensor and polymeric light emitting diodes (PLEDs) with yellow and turquoise emissions.

噻吩取代吩噻嗪聚合物：设计、合成和表征

摘要 本文以FeCl3为氧化剂，通过氧化聚合反应合成了含有吩噻嗪的聚合物。这些聚合物在其结构中包含醚单元、脂肪族链和芳香族基团作为桥。研究了这些基团对聚合物的光学、热学、形态学性质的影响。单体和聚合物的物理和化学性质通过FT-IR、NMR、UV-Vis、热重(TG)、循环伏安(CV)、荧光分析进行鉴定。根据荧光分析，含有脂肪醚桥的聚合物根据激发波长的转变发出黄色。含有脂肪醚桥的聚合物的黄色溶液在波长为 365 nm 的激发下变成了绿松石色。热分析表明含有苯桥化合物的聚合物有38%的残留量。由于荧光和热特性，这些聚合物可用于各种应用，例如分光荧光离子传感器和具有黄色和绿松石色发射的聚合物发光二极管 (PLED)。
