Since laser treatment of tattoos is the favored method for the removing of no longer wanted permanent skin paintings, analytical, biokinetics and toxicological data on the fragmentation pattern of commonly used pigments are urgently required for health safety reasons. Applying dynamic headspace-gas chromatography with mass spectrometric detection (DHS-GC/MS) and comprehensive two-dimensional ga...

Copper phthalocyanine can assemble along PPE backbones into molecular arrays and 2D assemblies with structural parameters different from its intrinsic 2D crystal. The template effect depends on the match between the size of phthalocyanine and the repeating period of the PPE backbone.

Several kinds of copper phthalocyanine-based conjugated microporous polymers have been synthesized, which present enhanced long-wavelength photon absorption capability and high efficiency for singlet oxygen generation under low energy light irradiation. This strategy opens a facile avenue towards expanding the scope of phthalocyanine-based porous materials with various internal structures and f...

An organic bulk heterojunction (BHJ) was fabricated using a blended film containing Copper (II) tetrakis(4cumylphenoxy)phthalocyanine (Tc-CuPc) along with [6,6]-Phenyl C61 butyric acid methyl ester (PCBM). Weight ratio between TcCuPc and PCBM was 1:1. The electrical properties of TcCuPc:PCBM BHJ were examined. Rectifying nature of the BHJ was displayed by current-voltage (I-V) curves, recorded ...

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...

Efficient out-of-plane charge transport is required in vertical device architectures, such as organic solar cells and organic light emitting diodes. Here, we show that graphene, transferred onto different technologically-relevant substrates, can be used to induce face-on molecular stacking and improve out-of-plane hole transport in copper phthalocyanine thin films.

Coordinate compounds of copper(II) are widely spread both as biological objects (metalloproteins and metallo-enzymes), and in engineering. Among the functions of the copper proteins are: the electron transfer involving the Cu(I)/Cu(II) couple; monoterminaloxidases, which form either water or hydrogen peroxide from dioxygen; oxygenases, which incorporate an oxygen atom into a substrate; superoxi...

A modified method for the synthesis of metallooctachlorophthalocyaninesand methods their purification based on sequential treatment with hydrochloric acid (10%) sodium hydroxide (2M), then again (10%), pyridine (O.S.C.) in 1,2,4-trichlorobenzene as a solvent is presented. As result, degree copper ion complexes was achieved, 99% versus best result using known literature 93%, cobalt purity 98% 88...

a series of schiff bases of ni(ii) and cu(ii) using acetylacetone (acac), salicylaldehyde (sal), ethylenediamine (en), and o-phenylendiarnine (dabe) were prepared and characterized. the electronic spectra of some copper chelates in various organic solvents depend strongly on the solvent used and the d-d band of cu(ii) shifts to red with the increase of the donor number (dn) of solvent. the colo...
