Background Complexing agents are widely used in various industrial processes and household products throughout the world. Amongst the well-known complexing agents, not only EDTA but also DTPA and NTA are widely used. Possible legislative restrictions of the use of biologically recalcitrant complexing agents brings about studies of novel and alternative products and at the same time more sophist...

a r t i c l e i n f o Thin-films and organic field-effect transistors fabricated from a solution-processable precursor of zinc tetra-benzoporphyrin (ZnTBP) are reported. Amorphous, insulating precursor films were deposited by spin-casting and thermally converted into polycrystalline, semiconducting thin-films comprising grains on the order of 5 μm in diameter. Thin-film X-ray diffraction indica...

The phthalodinitrile derivative (3) was prepared by the reaction of 4,4'-(octahydro-4,7-methano-5H-inden-5-ylidene)bisphenol (1) and 4-nitrophthalonitrile (2) with dry DMF as the solvent in the presence of the base K(2)CO(3) by the method of nucleophilic substitution of an activated nitro group in an aromatic ring. The template reaction of 3 with the corresponding metal salts gave the novel bi-...

A series of water-soluble tetrasulfonated metallophthalocyanines (MPcs) dyes have been studied to be used as a drug or photosensitizer (PS) in photodynamic therapy (PDT) for the treatment of cancers. During PDT the PS is administrated intravenously or topically to the patient before laser light at an appropriate wavelength is applied to the cancerous area to activate the PS. The activated PS wi...

The primary event in photosynthesis is the capture of sunlight by the light-harvesting antennas. These antennas absorb the sunlight and transmit the resulting singlet electronic excitation to the photochemical reaction centers.1,2 Disciplines Chemistry | Environmental Chemistry | Inorganic Chemistry | Organic Chemistry | Other Chemistry | Polymer Chemistry Comments Reprinted (adapted) with perm...
