title: Donor-acceptor-donor-type liquid crystal with a pyridazine core.
abstract: [structure: see text] A new liquid crystalline material having an ethylenedioxythiophene-pyridazine-ethylenedioxythiophene (EDOT-PDZ-EDOT) core with two peripheral long alkyl chains was prepared. The designated donor-acceptor-donor (D-A-D)-type core structure induced a distinct smectic liquid crystalline phase due to the strong intermolecular interaction. The photophysical property and the layer structure of the liquid crystal were investigated by differential scanning calorimetry, polarized light microscopy, X-ray diffraction, and cyclic voltammetry.
