Localization and migration of excess electron in aromatic substituted polyacetylenes in solution

Electron Transport with Mobility, μ > 86 cm2/(V s), in a 74 nm Long Polyfluorene

“…To put this conclusion in context of other reports, we estimated the diffusion coefficient and mobility of the electrons on the chains. In previous work we applied a well-known model describing random diffusion with coefficient D in 1-dimension, − to the transport of polarons and excitons on conjugated polymers. This model describes the time dependent probability of a charge attached randomly along chains of length L to survive being captured by absorbing traps at the chain ends (eq ).…”

Application of pulse radiolysis to the study of polymers and polymerizations

“…So far the radical anions of poly(methyl methacrylate) (PMMA) [46,47], substituted PMMA [46,47], poly(4-vinylbiphenyl) (PVB) [47-50], poly(1-vinylpyrene) (PVP) [50], organopolysilane [51] and substituted polyacetylene [52] have been studied. Subsequent electron attachment to solute polymers leads to the formation of polymer anions.…”

“…The structure of the radical anions of substituted polyacetylene is not clear, although the pulse radiolysis study on these polymers in solution is now in progress [52]. In this relevance, the absorption spectra of the radical anions of retinal homologues are interesting [55].…”
