Abstract
The polymers, polyazomethine (A), (B) and (D) were prepared by the condensation of glyoxal with diaminomaleonitrile, m-phenylenediamine-4-sulfonic acid and 2,4-diamino-phenol in DMF or DMSO respectively. The polymers. polyazomethine (C) and (E) were prepared by the condensation of terephthaldialdehyde with o-nitro -p- phenylenediamine and p-toluylenediamine in DMF respectively. IR absorption spectroscopy was used to elucidate the structure of polymers. The characteristic peak of polyazomethine. carbon-nitrogen double bond was found to absorb at 1620cm-1. It was insoluble in common organic solvents. Electrical conductivities of polyazomethines were measured by a 4-point probe technique. Polyazomethines without functional group, doped with Br2 and I2 showed higher electrical conductivity than polyazomethines with functional group, doped with Br2 and I2.

Polyazomethine (PAM) (A), (B), (D)는 glyoxal과 diaminomaleonitrile, m-phenylene diamine-4- sulfonic acid 그리고 2,4-diaminophenol을 용매로 N,N''-dimethylformamide (DMF)와 dimethylsulfoxide (DMSO) 하에서 중축합하고, PAM (C), (E)는 terephthaldialdehyde와 o-nitro-p-phenylenediamine, p-toluylenediamine을 용매로 DMF하에서 중축합하여 얻었다. PAM (A)-(E)의 IR spectra 분석결과 1620cm-1 부근에서 azomethine치 특성 peak인 -C=N-기 즉 schiff base 구조를 확인하였다. 이 중합물들은 인반적인 유기용매에 불용이고, 전기전도도는 4-point probe technique로 측정하였으며 Br2와 I2로 doping하였을 때 전기전도도는 측쇄에 극성기가 붙은 PAM이 극성기가 붙지 않은 PAM보다는 전기전도도가 약간 낮은 것으로 나타났다.
