Abstract: | Synthesic approach to polymers containing azo groups was developed on the basis of diazotization and azo-coupling reaction
of m-phenylenediamine (m-PDA) with various ratio m-phenylenediamine-sodium nitrite. Doping of poly(azoaminophenylenes) with iodine, perchloric and hydrochloric acids was examined.
Electroconductivity increases in the case of iodine to 0.2 S mol−1, of perchloric acid, to 7×10−3 S mol−1, and at the action of hydrogen chloride it is virtually unaffected. According to the ESR spectra, at the doping with iodine
and perchloric acid electroconductivity enhances generally due to the mobility increase of the charge carriers (polarons). |
