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...

CuI nanoparticles as an expedient and recyclable catalyst for the synthesis of N-cyclohexyl-3-aryl-quinoxaline-2-amines in ethanol via a multi-component reaction are established. The products were separated from the catalyst simply by filtration. The catalyst could be recycled and reused for several times without noticeably decreasing the catalytic activity.

Understanding the properties of synthetic copper-oxygen intermediates is important for evaluating mechanisms of oxidations by enzymes and other catalysts.1,2 A growing class of reactive copper-oxygen complexes have been isolated or identified spectroscopically to date, including well-studied examples with [Cu2(O2)], [Cu2(μ-O)2], or [CuO2] cores.3 Mononuclear copperoxo species ([CuII-O-• T CuIII...

We present a complete proof for the invariant optimal assignment for consecutive-k-outof-(2k+1):G cycle, which was proposed by Zuo and Kao in 1990 with an incomplete proof, pointed out recently by Jalali, Hawkes, Cui and Hwang.

A series of functionalized benzimidazo[1,2-c]quinazoline derivatives was obtained in excellent yields under mild conditions through a CuI-catalyzed Ullmann N-arylation starting from easily available starting materials.
