Through absorption of bromine vapor, the electrical conductivity of Polyphenylacetylene (PPA) enhanced by 1012 times. After pressing the bromine doped powder sample into pellet, we found that the conductivity of the samples increased with time. UVVis spectra, IR, and XPS spectra indicated that strong conjugation effect exists between PPA and bromine, and Charge Transfer Complex (CTC) is formed in PPA after doping; bromine doping increases the conjugation of PPA and improves its conductivity; the pressure can promote the doping effect of bromine on PPA.
