    Novel low-bandgap polyconjugated organic materials, oligo(azulene-1,3-diyl-vinylene)s, were prepared in a multistep synthesis starting from azulene. The key synthetic step was the olefin-metathesis-polycondensation of 1,3-diprop-1-en-1-ylazulene. Oligomeric products were isolated by column chromatography and characterized by mass-, 1H-NMR- and UV-Vis-NIR spectroscopy.

    Několikastupňovou syntézou byly připraveny nové polykonjugované organické materiály, oligo(azulene-1,3-diyl-vinyleny), s nízkou hodnotou zakázaného pásu. Oligomerní produkty byly izolovány sloupcovou chromatografií a charakterizovány hmotnostní, 1H-NMR- a UV-Vis-NIR spektroskopií.
