Abstract

For the first time we report on investigations of the electrical transport properties of multicomponent polymer systems based on [2-methoxy-5-(2'- etilgeksiloksi)-1,4-phenylene vinylene-] (MEH-PPV) molecules. The temperature dependences of dark conductivity on DC allow us to find a polaron mechanism of the charge transport with activation energy of 0.058 eV, which can be explained by an influence of phthalocyanine complex embedded in a polymer matrix as nanoimpurity. Theoretical calculations with Molecular Mechanics Universal Force Field (UFF) reveal that a set of Pc molecules has the dipole moment of 1.1276 Debye and its direction is from nitrogen atoms in the center of Pc ring to benzene groups in the periphery of the Pc molecule. Infrared optical spectroscopy data demonstrate that incorporation of the phthalocyanine complexes into the polymeric matrix leads to appearance of a set of the absorption lines in the region of 750/3340 cm-1.
