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.
