The formation of coordination polymers (CuCl)P4Se3 (1), (CuBr)3(P4Se3)2 (2), (CuI)3(P4Se3)2 (3) and (CuI)P4Se3 (4), from solutions of copper(I) halides and P4Se3 by diffusion methods has been studied. The new compounds were characterized by X-ray crystallography, solid-state P MAS NMR and Raman spectroscopy. Theoretical studies on the DFT level in the crystalline phase allowed the unequivocal a...

Ever since Czech writer Karel Capek's well-known play " R.U.R. – Rossum's universal robots " [Capek], first published in 1920 and performed in 1921, man-made robots of human-like shape have inspired fiction writers to envision worlds with artificial creatures far superior to human beings – either in friendly coexistence or taking over by eliminating their creators and leaving them behind as an ...

Introduction To facilitate radiotracers' development, a screening methodology using a biomathematical model and clinical usefulness index (CUI) was proposed to evaluate radiotracers' diagnostic capabilities. Methods A total of 31 amyloid positron emission tomography radiotracers were evaluated. A previously developed biomathematical model was used to simulate 1000 standardized uptake value ra...

The crystal structures of two mixed-valence copper cyanide compounds involving N-methyl-ethylenedi-amine (meen), are described. In compound (I), poly[bis(μ3-cyanido-κ3C:C:N)tris(μ2-cyanido-κ2C:N)bis(N-methylethane-1,2-di-amine-κ2N,N')tricopper(I)copper(II)], [Cu4(CN)5(C3H10N2)2] or Cu4(CN)5meen2, cyanide groups link CuI atoms into a three-dimensional network containing open channels parallel to...

The present work introduces the solvent exchange procedure as a route for conversion of Cu4I4L2 complex, where Cu4I4 cluster core is coordinated with two P,N-ligands (L), into an aqueous colloid. analysis both colloidal and supernatant phases revealed some losses in CuI going from initial complex to Cu2I2L3-based nanoparticles. comparative IR, 31P NMR spectroscopy, ESI mass-spectrometry lumines...

Morphological and structural control of organic semiconductors through structural templating is an efficient route by which to tune their physical properties. The preparation and characterisation of iron phthalocyanine (FePc)-copper iodide (CuI) bilayers at elevated substrate temperatures is presented. Thin CuI(111) layers are prepared which are composed of isolated islands rather than continuo...

Reactions between copper(I) iodide and triphenylphosphine have been explored in solution and in the solid state and six luminescent coordination complexes have been obtained and characterized by X-ray diffraction and UV-vis spectroscopy and photophysics. Solid-state reactions of CuI with PPh(3) in different conditions (kneading, vapour digestion) and stoichiometries resulted in the formation of...
