    Electrical and thermal properties of anthrone
    (Wydawnictwo Politechniki Łódzkiej, 2020) Kania, Sylwester; Kuliński, Janusz; Sikorski, Dominik
    Quantum-chemical density functional theorem (DFT) calculations indicate that the value of the reorganization energy indicates the possibility of efficient hole capture by the anthrone molecule during transport process of charge carriers. Differential scanning calorimetry (DSC) studies indicate the temperature stability of anthrone molecules above the melting point up to 164°C. The glass transition is determined at 153.7 °C and melting point at 157.05 °C.

    Electrical and thermal properties of anthraquinone layers
    (Lodz University of Technology Press, 2019) Kania, Sylwester; Kuliński, Janusz; Sikorski, Dominik
    Quantum-chemical calculations indicate that the bond lengths in the anthraquinone anthracene backbone are shorter than the corresponding bonds in unsubstituted anthracene. The shape of the frontier molecular orbitals (FMO) indicates the possibility of more efficient electron capture by the anthraquinone molecule than by the anthracene molecule while maintaining stability in the conditions prevailing in electrochemical cells. Differential scanning calorimetry (DSC) studies indicate the temperature stability of anthraquinone above the melting point up to 300C. The glass transition is determined at about 100°C.
  • Pozycja
    The origin of the interaction responsible for the difference of hole mobility of thwo derivatives of anthracene
    (Wydawnictwo Politechniki Łódzkiej, 2018) Kania, Sylwester; Kuliński, Janusz; Sikorski, Dominik
    Hole mobility of the layers built from two anthracene derivatives differing in the substitution of the central benzene ring, i.e. anthrone substituted with only one keto group and anthraquinone substituted with two keto groups differs by one order of magnitude despite the fact that both have almost identical crystal structure. We ascribe this difference to existence of an additional intermolecular interaction arising in the layer of anthrone.

    Comparative study of the influence of the reorganization energy on the hole transport of two four-cyclic arenes
    (Wydawnictwo Politechniki Łódzkiej, 2017) Kania, Sylwester; Kuliński, Janusz; Sikorski, Dominik
    Application of the method of quantum-mechanical calculations allowed the determination of the reorganization energy of the molecules of tetracene and p-quaterphenyl and the estimation of the transfer rate integral between neighbouring molecules present in the solid state. Comparison of the transfer rates for holes with the values of the mobility, obtained experimentally for the polycrystalline tetracene layers and p-quaterphenyl layers vaporized in the vacuum in the similar conditions indicate that the molecule’s structure possess the dominate impact on the conductivity of the thin layers of these compounds.
