摘要	We investigated the electron paramagnetic resonance (EPR) spectra of undoped, FeCl3- and iodine-doped poly(para-phenylene) (PPP) prepared by the method of Kovacic. EPR measurements are used to characterize electronic states relevant for carrier transport in doped PPP. We found a novel dependence of room temperature linewidth (DELTAH(pp)) and spin density (N(spin)) on the dopant concentrations for iodine-doped PPP, namely, DELTAH(pp) first decreased and increased, and then decreased and increased again with increasing iodine concentration in the iodine-doped PPP. The corresponding value of N(spin) first increased and decreased, and then increased and decreased again with increasing iodine concentration in PPP. However, the changes in DELTAH(pp) and N(spin) with FeCl3 concentration in FeCl3-doped PPP differ from those of iodine-doped PPP. We explain the different EPR properties in FeCl3-doped and iodine-doped PPP.
