説明

Electron-nuclear double-resonance (ENDOR) spectra of undoped poly(paraphenylene vinylene) are well described by the spin density distribution of the polaron for finite electron-electron interactions. Theoretically calculated spin distribution using the Pariser-Parr-Pople model with intermediate strength of the interactions yields the maximum spin density of 0.09 at vinylene sites with the half-width of the distribution over four PPV monomer units. The non-monotonic form of distribution together with the signs of spin densities are confirmed with the ENDOR-induced ESR as well as electron-nuclear-nuclear triple resonance (TRIPLE). The observed extension of the polaron is larger than that of the soliton reported in polyacetylene, which may be related to the nature of the polaron in conjugated polymers being viewed as a bound soliton pair.
