Polyaniline (PANI) nanocomposites were synthesized by incorporating separately synthesized metal nanoparticles in 1-methyl-2-pyrrolidinone (NMP) solution of polyaniline. PANI was prepared by oxidative reduction of aniline using chemical method. Silver nanoparticles were produced by inert gas condensation; whereas gold nanoparticles were synthesized by the reduction of gold salt. FTIR confirmed the formation of PANI in all samples. The electrical properties of the nanocomposites were determined by impedance spectroscopy. The conductivity relaxation analysis suggested microphase separation of NMP plasticized films into phases of reduced and oxidized repeat units. The conductivity of PANI films increases with the increase in concentration of embedded nanoparticles. Incorporation of metal nanoparticles in PANI causes considerable decrease in the real part of impedance.

In this work, the investigation of structural features, spectral and electrical properties of spin-coated films of substituted lutetium bisphthalocyanine Lu ( Pc ( SR )8)2, where R = - C 6 H 13 was carried out. The current-voltage characteristics of ITO/ Lu ( Pc ( SR )8)2/ Al film sandwich structures were measured over the temperature range 120–380 K. AC electrical properties, mainly the dependence of conductance and capacitance on frequency and temperature are also discussed. Structural and electrical properties of anthracene-doped Lu ( Pc ( SR )8)2, films have also been investigated. Furthermore, optical properties of thin films of pure and anthracene-doped Lu ( Pc ( SR )8)2 films were also studied using spectroscopic ellipsometry, while atomic force microscopy (AFM) was used to study changes in films' morphology of doped films and compared with that of undoped films. Doping Lu ( Pc ( SR )8)2, films with anthracene is shown to lead to an increase in films' conductivity. These studies will provide full understanding of the physical properties of the Lu ( Pc ( SR )8)2, thin films, both doped and undoped, with the aim of exploitation in electronic device applications, such as fabrication of all organic solar cells.
