Raman Spectra of Highly Conducting Poly-p-phenylene Complexes.

Abstract

The resonance Raman spectra of poly(p-phenylene) (PPP) and the highly conducting materials formed by doping it with the electron-donor Na (Na-PPP) or the electron acceptor AsF5 (AsF5-PPP) have been obtained. Doping with either type of dopant causes the C-C bond joining the phenyl-rings to become stronger and at least one of the in-ring bonds to become weaker, so all C-C bonds along the backbone of the pi-electron system become more alike than they are in the undoped PPP. The resonance enhancements show the relationship between changes in molecular configuration caused by optical transitions in the donor- or acceptor-doped PPP materials and the vibrational modes of the polymer.
