One-electron oxidation of the 1,2,4-diazaphospholide anion [3,5-R2dp]- by BiCl3 generated several remarkable paddlewheel dibismuthanes [L2(Bi-Bi)L2] (L = η1,η1-3,5-R2dp, R = tBu, iPr, or Ph) with very short Bi-Bi single bond lengths (2.7964(4)-2.8873(3) Å). © 2015 The Royal Society of Chemistry.

Several structurally characterized heteroleptic, charge-separated heterobimetallic, and polymeric alkali metal ate complexes of 1,2,4-diazaphospholide Y(iii), Dy(iii), Er(iii), Eu(iii), and Eu(ii) were prepared via the reaction of MCl3 and K[3,5-R2dp] in varied ratios at 200-220 °C (M = Y, Dy, Er, Eu; R = tBu, Ph). © The Royal Society of Chemistry 2016.

The oxidation of 1,2,4-diazaphospholide potassium (K+[2-]) produces a neutral 1,2,4-diazaphospholyl radical (2•) which can subsequently afford the 2(N)-2(P) dimer involving a N-P linkage. © The Royal Society of Chemistry 2015.

Using the ab initio density-functional theory method, we calculated the size effect and edge shape effect on UV-visible light absorption of different shapes of graphene quantum dots (GQDs). There are two interesting findings in this study. First, the edge shape effect increase with increasing the size of square GQDs. Second, the Seam atoms, located at the boundary between zigzag and armchair edges, hardly contribute to the strongest visible light absorption. This refinement of the edge-shape effect can be found in rectangular, triangular and hexagonal GQDs. This new finding will be useful in applications of GQDs in the visible light absorption nanodevices. © 2014 Elsevier B.V.

The oxide-based diluted magnetic semiconductors (DMSs) with Curie temperatures, Tc, at or above room temperature (RT) have attracted great interest due to their potential applications in spintronic devices.1 Among them, the Fe-doped In2O3 DMS has attracted considerable interest because of the high solubility of Fe in the In2O3 matrix, excellent electrical conductivity, and high optical trans-parency.2,3 In the past decades, many research activities have been focused on the bulk and thin films of Fe-doped In2O3. However, due to the advantages of their small size, low-dimensional characteristics and unique magnetic properties, magnetic semiconductor nanodot arrays provide a promising way to apply spin-dependent functions to semiconductor microelectronics and nanotech-nology.4 With this motivation, here we present the first study of growing Fe-doped In2O3 nanodot arrays on Al2O3 (0001) substrates using the pulsed laser deposition (PLD) with the aid of porous anodized aluminum (PAA) templates, and provide the insights into the origin of the RT ferromag-netism in Fe-doped In2O3 nanodot arrays by a comprehensive analysis of structure, morphology and magnetic properties of the arrays. © 2015 IEEE.
