摘要：

Poly(2-bromo-5-hexyloxy-p-phenylenevinylene), BHPPV, was electrochemically synthesized in 81% yield. The polymer presented high solubility in organic solvents, in spite of its relatively high molar weight (<(M)over bar (W)> = 80 000), and showed to be thermally resistant UP to 130 degrees C. Gas sensors made from thin films of CSA doped BHPPV, deposited on interdigitated electrodes, responded to five different solvents. Plots of relative response versus relative recovery showed good discrimination of the five solvents.
