Polyphenylene having not only solubility in organic solvents but electrical conductivity was prepared by using n-butyllithium as a initiator and 1,4-dibromobenzene as a monomer through the Wurtz coupling reaction under a variety of the reaction conditions. Spectroscopic analysis provided an information about side reactions generating n-butyl branch in the phenyl ring of the main chain as well as hydroxy group resulting from the reaction of organolithium with tetrahydrofuran. The amounts of n-butyl branch attached on the pheny1 ring were 52.9% ∼8.20%.

유기용제에 가용성이며 적절한 전기전도도를 갖는 폴리페닐렌을 Wurtz coupling reaction을 통하여 단량체를 1,4-dibromobenzene과 개시제로 n-butyllithium을 사용하여 반응조건을 변화시키면서 합성하였다. 이 때 발생하는 부반응에 대하여 spectroscopy를 통하여 조사한 결과 main chain의 phenyl ring에 f-butyl기의 attachment와 THF와의 부반응이 발생하여 부산물인 n-butyl branch를갖는 폴리페닐렌이 합성되었다. Phenyl ring에 attachment된 n-butyl기의 양은 52.9%∼8.20%였다.
