The data obtained via X-ray scattering and transmission electron diffraction show that, for both K-doped terphenyl and quaterphenyl samples, there is an increase in the <i>c</i> parameter. However, in regard to Na-doped terphenyl, there is a <i>c</i> parameter decrease along with an <i>a</i> parameter increase, which may be accounted for by the polymerization of this oligomer. Moreover, in order to complete the crystallographic study, a Raman analysis was conducted to describe the localization of the radical anions and the local distortions induced by the electric charges during the doping process.Molecules (Basel, Switzerland)8699https://www.ebi.ac.uk/biostudies/studies/S-EPMC9785341biostudies-literatureThe Influence of Alkali Metals on the Doping of Poly(<i>p</i>-phenylene) Oligomers.PMC9785341da Rochas Rodrigues RLouarn GPeres LOfalseThe Influence of Alkali Metals on the Doping of Poly(<i>p</i>-phenylene) Oligomers.In this study, we report on crystallographic studies that were performed on Na- and K-doped terphenyl and quaterphenyl.
