The polymers, polyazomethine(Ⅶ), (Ⅷ) and (Ⅸ) were prepared by the condensation of 2,6- diaminopyridine with glyoxal. diacetyl and benzoquinone in DMSO. respectively. Hydrochloric acid-salts of polyazomethine(Ⅶ), (Ⅷ) and (Ⅸ) were prepared by stirring in aqueous HCl of various selected concentrations. Electrical conductivity was measured by a 4-point probe technique. All the undoped polymers were insulators having electrical conductivity of the order of 10^-l0 Ω^-1cm ^-1. By doping with bromine or iodine, the electrical conductivity increased by several orders of magnitude and reached a value of 10^-2∼10^-3 Ω^-1cm^-1. Hydrochloric acid-salts of polyazomethine( Ⅶ), (Ⅷ) and (Ⅸ) showed electrical conductivity of 10^-1∼10^-2 Ω^-l cm^-1, that is. ten times greater than those of polyazomethine doped with bromine or iodine.

Polyazomethine (Ⅶ), (Ⅷ) 및 (Ⅸ)를 2,6-diaminopyridine과 glyoxal, diacetyl 그리고 benzoquinone으로 DMSO하에서 중축합하여 얻었으며 polyazomethine (Ⅶ), (Ⅷ)과 (Ⅸ)를 정해진 pH의 염산수용액 속에서 반응시켜 염산염을 얻었다. 전기전도도는 4-point probe technique으로 측정하였다. 합성된 polymers는 모두 10^-10Ω^-1㎝^-1 전도의 전기전도도를 갖는 부도체였으며, Br₂나 I₂ 로 doping하였을 때 전도도가 향상되어 10^-2∼10^-3Ω^-1㎝^-1가 되었고, polyazomethine (Ⅶ), (Ⅷ)과 (Ⅸ)의 염산염의 전기전도도는 10^-1∼10^-2Ω^-1㎝^-1로 Br₂나 I₂로 doping한 것보다 10배정도 높게 나타났다.
