A new assessment of the crystalline structure of undoped and doped aniline oligomers and polymers

Abstract

We describe here the crystalline structure of aniline oligomers and polymers, derived from the aniline dimer, p-aminodiphenylamine, and aniline. It is shown that while the crystalline structure of the undoped samples is generally in reasonable accord with the findings of Pouget et al. for their EBII-structure, especially the crystalline arrangement of the doped materials does not fit the picture, given by these authors for the ESII-salt. The latter fact might be rationalized by the simple exchange of the two main peaks of the ESII arrangement, thus giving the P21221 arrangement, proposed by Pouget et al. but not found in their experimental studies. © 1995.
