Abstract
Conjugated oligomers with ethynylpyridazine units have been synthetized by Sonogashira and Suzuki cross-coupling reactions. Some of them present interesting liquid crystals properties investigated by differential scanning calorimetry (DSC) and polarized light microscopy. Some of these oligomers are fluorescent.
