Reaction of 5-phenyl-2,2'-bipyridine (L) with a mixture of CuI or [Cu(CH3CN)4]BF4 and PPh3 leads to mononuclear heteroleptic complexes [CuL(PPh3)I] (1) and [CuL(PPh3)2]BF4 (2). According to X-ray diffraction, L crystallizes in the monoclinic space group P21/n, exhibiting a disorder over four orientations. Complexes 1 and 2 crystallize in the monoclinic space groups P21/c and P21, respectively. ...

Die Langzeitstabilität des optisch transparenten p-Typ-Halbleiters Kupferiodid ist eine aktuelle Herausforderung, da die elektrische Leitfähigkeit von CuI-Dünnfilmen empfindlich auf Umgebungseinflüsse reagiert. Deckschichten aus Aluminiumoxid erhöhen Stabilität beträchtlich. Systematische Untersuchungen Al2O3/CuI-Heterostrukturen in Abhängigkeit der N2- oder O2-Partialdrücke bei Oxid-Abscheidun...

In this work, planar heterojunction organic photovoltaic cells (PHJ-OPVs) based on alpha-sexithiophene (α-6T) and fullerene active materials were investigated. We have studied the effect of hole transporting layer (HTL) performances PHJ-OPVs. The HTLs are molybdenum trioxide (MoO3), cuprous iodide CuI MoO3 coupled with (MoO3/CuI). PHJ-OPVs fabricated using thermal evaporation/sublimation techni...

Utilizing X-ray crystallography, the crystal and molecular structures of 2,6-diacetylpyridine bis(phenylhydrazone) (L) were determined. The energetics intermolecular interactions in structure assessed with computational methods, revealing that dispersion are dominant. basic structural unit packing was revealed to be herring- bone type arrangement L molecules. Assignation IR spectrum aid DFT cal...
