Complexes of 1,2-bis(aryl-imino)acenaphthene (Ar-BIAN) ligands with some heavy p-block elements

The new Ar-BIAN complexes [(mes-BIAN)InCl(3)(THF)] (1), [(mes-BIAN)(2)Tl][PF(6)] (2), [(dipp-BIAN)SnCl(4)] (3), [(dipp-BIAN)SbCl(3)] (4), [(dipp-BIAN)BiCl(3)] (5) and [(mes-BIAN)BiCl(3)] (6) have been prepared by treatment of the neutral mes- and dipp-substituted BIAN ligands with the p-block reagents InCl(3), TlPF(6), SnCl(4), SbCl(3), and BiCl(3). The molecular structures of complexes 1-6 have been determined by single-crystal X-ray diffraction methods. However, only the atom connectivity was established for 5.     

Controlling the oxidation state of arsenic in cyclic arsenic cations

Reduction of AsCl3 with SnCl2, followed by treatment of the "AsCl" with a 1,4-diimine results in electron transfer and formation of an arsenic(III) salt, while treatment of this arsenic(I) reagent or AsI3 with an alpha,alpha'-diiminopyridine ligand forms an arsenic(I) salt.     

An N,N'-chelated phosphenium cation supported by a beta-diketiminate ligand

The first example of a phosphenium cation supported by N,N'-chelation of a beta-diketiminate ligand has been prepared and structurally characterized.     

Fatou closedness under model uncertainty

We provide a characterization in terms of Fatou closedness for weakly closed monotone convex sets in the space of \({\mathcal P}\)-quasisure bounded random variables, where \({\mathcal P}\) is a (possibly non-dominated) class of probability measures. Applications of our results lie within robust versions the Fundamental Theorem of Asset Pricing or dual representation of convex risk measures.     

Phase diagram of pentacene growth on Au(110)

We studied the growth of pentacene (C22H14) on the Au(110) surface by means of He atom scattering and Synchrotron X-ray photoemission. We found that two-dimensional commensurate growth only occurs in the monolayer range for a substrate temperature, T(s), higher than approximately 370 K. Larger amounts of deposited molecules forms three-dimensional uncorrelated clusters on the wetting layer. The desorption of second layer molecules occurs at T(s) > or = 420 K. The highest coverage ordered phase displays a (6 x 8) symmetry and corresponds to the saturation coverage at T(s) = 420 K. The (3 x 6) symmetry phase, recently reported for a multilayer planar film [Ph. Guaino, et al. Appl. Phys. Lett. 2004, 85, 2777], is only found at a coverage slightly lower than the (6 x 8) one. The (3 x 6) phase corresponds to the saturation coverage of the first layer at T(s) = 470 K.     

Continuity properties of law-invariant (quasi-)convex risk functions on <Emphasis Type="Italic">L</Emphasis><Superscript>∞</Superscript>

We study continuity properties of law-invariant (quasi-)convex functions \({f:L^\infty(\Omega, \mathcal{F}, \mathbb{P}) \to (-\infty,\infty]}\) over a non-atomic probability space \({(\Omega, \mathcal{F}, \mathbb{P})}\). This is a supplementary note to Jouini et al. (Adv Math Econ 9:49–71, 2006).     

A Titanium(IV)‐Based Metal–Organic Framework Featuring Defect‐Rich Ti‐O Sheets as an Oxidative Desulfurization Catalyst

While titanium‐based metal–organic frameworks (MOFs) have been widely studied for their (photo)catalytic potential, only a few Ti^IV MOFs have been reported owing to the high reactivity of the employed titanium precursors. The synthesis of COK‐47 is now presented, the first Ti carboxylate MOF based on sheets of Ti^IVO₆ octahedra, which can be synthesized with a range of different linkers. COK‐47 can be synthesized as an inherently defective nanoparticulate material, rendering it a highly efficient catalyst for the oxidation of thiophenes. Its structure was determined by continuous rotation electron diffraction and studied in depth by X‐ray total scattering, EXAFS, and solid‐state NMR. Furthermore, its photoactivity was investigated by electron paramagnetic resonance and demonstrated by catalytic photodegradation of rhodamine 6G.
