Synthesis of aniline fragment containing polimers linked with different groups

Abstract

Utilizing cost-effective and readily available monomers in conjunction with industrially employed methodologies, novel electroactive polymers have been successfully synthesized. These polymers incorporate aniline oligomers covalently linked through triazenarylene groups. The resulting polymers effectively combine the distinctive features of polyaniline (PANI) and linking group, thus expanding the range of polyaniline applications. To carry out the syntheses p-phenylenediamine, benzidine were used as monomers, the applied methods are oxidation-condensation and diazotization, azocombination. It has been shown that the electrical conductivities of iodine-doped polymers are approximately of the same order as the electrical conductivities of polyaniline, determined in the same way. Polymers containing 1,4-ditriazen-3-yl benzidine units have been shown to have higher electrical conductivity for the same length of oligoaniline chains. The resulting polymers exhibit fluorescent properties.
