【摘要】 在共轭高分子材料的研究中，聚苯一直是人们关注的热点之一［1～4]，但聚苯的不溶和不熔性大大限制了其应用前景，因而可溶性聚苯的开发研究成为目前的一种趋势．合成测基带有烷基和烷氧基的聚苯已有报道［5，6］，我们曾会成了侧基带有强推电子基团的可溶性聚苯——聚（N...更多还原

【Abstract】 A study of polyphenylene (PP) is always a focus in all kinds of the conjugated polymers. Based on synthesis of poly (N, N-dimethylaniline ) (PDMA ), polynitrobenzene (PNB) is obtained by modifying PDMA with concentrated nitric acid in acetic anhydride.This new nitro-substituted PP is soluble in common organic solvents such as acetone, DMF and THF at room temperature. Thls paper describes the synthetic process and confirms the characteristic of PNB by elementary analysis, NMR, FTIR and UV-Vis spectra, then discusses a possible reaction mechanism.更多还原
