✦ Synopsis
Chain-length-dependent a electron delocalization is analyzed in pristine oligofurans and polyfuran by means of Fourier transform Raman spectroscopy. Neutral polyfuran shows a large frequency dispersion with conjugation length and it has not yet reached saturation at the level of the hexamer. In spite of such a large a electron delocalization the polymer seems to show an unexpectedly good stability in air at room temperature. Regio-defined poly(2,5-difurans) could be good candidates for technological developments.
