چکیده انگلیسی
We synthesized nanotubes and nanowires of Ï-conjugated polythiophene (PT) and poly (3-methylthiophene) (P3MT) by using nanoporous anodic aluminum oxide (A12O3) template through electrochemical polymerization method From SEM and TEM photographs, we observed the formation of nanotubes with diameters of 100 â¼Â 200 nm and wall thicknesses of 5 â¼Â 10 nm. The length of PT and P3MT nanotubes and nanowires was up to â¼40 μm. To discern the structural and optical properties of the systems, we measured UV/Vis absorbance and FT-IR spectra. We observed that the doping level, the Ï-Ï* transition peak, and bipolaron peaks in P3MT nanotubes varied with synthetic temperature. Based on measured I-V characteristic curves with gate bias for a single strand of PT nanotube, the systems should be considered to exhibit p-type nature.
