Abstract

ESR spectra show that the number of paramagnetic centers in polyphenylacetylene (PPA) is linearly related to the oxygen pressure; iodine has an even more marked effect, the limiting concentration (7×1018 spins per g) being reached for a molar ratio of PPA to iodine of 1∶6. The central part of the ESR line is lorentzian, with gaussian wings. A Lorenz curve fits a large fraction of the spectrum for PPA-iodine. The delocalization region for the unpaired electron corresponds to two units of PPA for oxygen and one for iodine. The results are interpreted in terms of charge-transfer complexes (CTC) between the PPA and electron acceptor (oxygen or iodine). Microwave saturation occurs in pumped PPA; loss of saturation is related to the formation of CTC.
