By using 1,5-pentanediol as a capping and structure directing agent, ultrathin Eu2O3 nanosheets (<1 nm) have been synthesized and assembled into a layered structure. The lateral dimensions of the nanosheets can be tuned by simply controlling the reaction time. These layered structures exhibit a strong quantum size effect due to the extremely small thickness… (More)
A photonic integrated circuit (PIC) is the optical analogy of an electronic loop in which photons are signal carriers with high transport speed and parallel processing capability. Besides the most frequently demonstrated silicon-based circuits, PICs require a variety of materials for light generation, processing, modulation, and detection. With their… (More)
The reaction mechanisms for the reduction of carbon dioxide to formaldehyde catalyzed by bis(tricyclopentylphosphine) metal complexes, [RuH 2 (H 2)(PCyp 3) 2 ] (1 Ru), [FeH 2 (H 2)(PCyp 3) 2 ] (1 Fe) and [OsH 4 (PCyp 3) 2 ] (1 Os), were studied computationally by using the density functional theory (DFT). 1 Ru is a recently reported highly efficient… (More)
"H"-like organic nanowire heterojunctions with two parallel 2-acetyl-6-dimethylamino-naphthalene wires vertically bridged by one 2,4,5-triphenylimidazole wire are prepared via cooperative molecular assembly in liquid phase. The exciton conversion at the junction interfaces is beneficial for the design of multichannel light-controlled photo-switches. The… (More)
Because of their outstanding molecular optoelectronic properties, perylene diimides (PDIs) are promising alternatives to the commonly used PCBM. However, the overly strong aggregation ability, poor solution-processability and compatibility of PDIs severely limit their photovoltaic applications. We turned to borrowing the amphiphile concept to improve these… (More)
The electrogenerated upconversion was achieved in the uniformly doped organic nanowires based on triplet energy transfer from tris(2,2'-bipyridyl)ruthenium(II) to 9,10-diphenylanthracene.
The title mol-ecule, C(25)H(21)N(5)O(8), adopts a helical conformation, which is stabilized by two intra-molecular bifurcated N-H⋯(N,N) hydrogen bonds.
