摘　　要：Poly(p-phenylene) (PPP) microtubules with diameters of 0.2-0.8μm and lengths of～10 (m have been synthesized by direct oxidation of benzene in the mixed electrolyte of boron trifluoride diethyl etherate (BFEE) and trifluoroacetic acid (TFA) (BFEE:TFA= 2:1, by volume), containing a certain amount of sodium dodecylbenzene- sulfonate (SDBS) as surfactant. The microtubules were grown vertically on the working electrode surface. The tubular morphology has been confirmed by scanning and transmission electron microscopies and the chain structure of the skin of the tubules has been characterized by Raman spectroscopy. The electrode property, monomer/surfactant molar ratio and the value of applied potential have strong effects on the morphology of the microtubules.Poly(p-phenylene) (PPP) microtubules with diameters of 0.20.8 mm and lengths of ~10 mm have been synthesized by direct oxidation of benzene in the mixed elec-trolyte of boron trifluoride diethyl etherate (BFEE) and trifluoroacetic acid (TFA) (BFEE︰TFA= 2︰1, by volume), containing a certain amount of sodium dodecylbenzene- sul-fonate (SDBS) as surfactant.
