Abstract
Chain-length-dependent pi electron delocalization is analyzed in prist ine oligofurans and polyfuran by means of Fourier transform Raman spec troscopy. Neutral polyfuran shows a large frequency dispersion with co njugation length and it has not yet reached saturation at the level of the hexamer. In spite of such a large pi electron delocalization the polymer seems to show an unexpectedly good stability in air at room te mperature. Regio-defined poly(2,5-difurans) could be good candidates f or technological developments.
