As a particular class of planar aromatic compounds, metal phthalocyanines are considered for numerous applications since they show a variety of interesting physical and chemical properties. In particular, the semiconducting copper phthalocyanine (CuPc), is employed in several optoelectronic devices such as organic light-emitting diodes or organic photovoltaic cells. The ambipolar charge carrier...

Recent lightwave-STM experiments have shown space and time resolution of single molecule vibrations directly on their intrinsic length timescales. We address here theoretically the electronic dynamics a copper-phthalocyanine in explored within pump-probe cycle scheme. The spin-orbit interaction metallic center induces beatings electric charge flowing through as function delay between pump probe...

Electroreflection and Raman spectra (in situ and ex situ) of zinc phthalocyanine (ZnPc) films (80 nm thick) have been studied. Raman spectra were resonantly and preresonantly enhanced. Both electroreflection and Raman experiments reveal the homogeneous inclusion of electrolyte anions upon oxidation of the film. The anions coordinate preferentially axial positions of the ZnPc molecule. This proc...

This thesis describes the calculation of exchange interactions for systems of electrons, and their potential uses for quantum information processing. The first part treats exchange between donor impurities (including especially deep donors) in silicon, while the second describes exchange in copper and manganese phthalocyanines. Part I uses the quantum defect method and a model central-cell corr...

Phthalocyanines, a class of macrocyclic, square planar molecules, are extensively studied as semiconductor materials for chemical sensors, dye-sensitized solar cells, and other applications. In this study, we use angular dependent near-edge x-ray absorption fine structure (NEXAFS) spectroscopy as a quantitative probe of the orientation and electronic structure of H2-, Fe-, Co-, and Cu-phthalocy...

Novel copper phthalocyanine (CuPc) materials have potential applications in solar cells, fuel cells, optical-limiting materials, gas sensors and field-effect transistors. Most recently there have been interests in applications for high dielectric constant material for capacitors. For example, Zhang et al. have reported a dielectric constant of 48 at 1MHz in an electrostrictive polymeric CuPc/Po...
