Micro‐ to Macroscopic Observations of MnAlPO‐5 Nanocrystal Growth in Ionic‐Liquid Media
Authors: Ng Eng‐Poh , Itani Lama , Sekhon Satpal Singh , Mintova Svetlana 
Published: September 2010

AbstractMicro‐ and macroscopic studies of nucleation and growth processes of MnAlPO‐5 nanosized crystals under ionothermal synthesis conditions are reported herein. The samples treated at 150 °C were extracted from the reaction mixture at various stages of crystallization, and characterized by XRD; SEM; thermogravimetric analysis (TGA); 31P and 27Al solid‐state magic angle spinning (MAS) NMR, Raman, UV/Vis, and X‐ray fluorescence spectroscopy (XRF). The starting raw materials (alumina, manganese, and phosphorous) were dissolved completely in the ionic liquid and transformed into an amorphous solid after 5 h of ionothermal treatment. This amorphous solid then undergoes structural changes over the following 5–25 h, which result in an intermediate phase that consists of octahedral Al species linked to the manganese and phosphate species. The first MnAlPO‐5 nuclei on the surface of the intermediate can be observed after 50 h ionoheating. These nuclei further grow, as the surface of the intermediate is in full contact with the ionic liquid, to give crystalline MnAlPO‐5 nanoparticles with a mean diameter of 80 nm. The crystals become fully detached from the intermediate and are then liberated as discrete particles after 90 h heating. The transformation process from amorphous to intermediate and then to the crystalline MnAlPO‐5 nanoparticles shows that nucleation starts at the solid–liquid interface and continues through surface‐to‐core reversed‐growth until the entire amorphous solid is transformed into discrete nanocrystals.
Effect of pH and Counterions on the Encapsulation Properties of Xenon in Water‐Soluble Cryptophanes

Published: September 2010

AbstractIn the 129Xe NMR‐based biosensing approach in which the hyperpolarized noble gas is transported to biological receptors for a sensitive molecular imaging, cryptophanes are excellent xenon host systems. However to avoid formation of self‐organized systems, these hydrophobic cage molecules can be rendered water soluble by introduction of ionic groups. We show that the sensitivity of xenon to its local environment and the presence of these ionic functions can lead to interesting properties. For a first water‐soluble cryptophane derivative, we show that a precise monitoring of the local pH can be performed. For a second cryptophane, the presence of ionic groups close to the cryptophane cavity modifies the xenon binding constant and in–out exchange rate. The latter allows the tuning of physical properties of xenon–cryptophane interactions without resorting to a change of the cavity size. These results open new perspectives on the influence of chemical modifications of cryptophanes for optimizing the biosensor properties.
An Ir–Pt Catalyst for the Multistep Preparation of Functionalized Indoles from the Reaction of Amino Alcohols and Alkynyl Alcohols
Authors: Zanardi Alessandro , Mata Jose A. , Peris Eduardo 
Published: September 2010

AbstractThe 1,2,4‐trimethyltriazolylidene (ditz) ligand allows the preparation of homo‐ and heterodimetallic complexes of Pt2 and Ir–Pt. These two complexes have been characterized by means of spectroscopic and diffractommetric techniques. The catalytic activity of these complexes, together with that of other Pt‐based compounds, has been explored in the cyclization–addition of alkynyl alcohols and indoles. The Ir–Pt complex [{PtI2(py)}(μ‐ditz){IrI2(Cp*)}] (py=pyridine; Cp*=pentamethylcyclopentadienyl) allows the combination of an iridium‐mediated oxidative cyclization of 2‐(ortho‐aminophenyl)ethanol to form indoles, with a further step employing a Pt‐based multistep reaction that functionalizes indoles. Our results show that the Ir–Pt complex is a very active catalyst in this new multistep preparation of functionalized indoles from the reaction of an amino alcohol with alkynyl alcohols.
Cationic versus Neutral RuIIN‐Heterocyclic Carbene Complexes as Latent Precatalysts for the UV‐Induced Ring‐Opening Metathesis Polymerization
Authors: Wang Dongren , Wurst Klaus , Buchmeiser Michael R. 
Published: September 2010

AbstractA series of cationic and neutral RuII complexes of the general formula [Ru(L)(X) (tBuCN)4]+X− and [Ru(L)(X)2(tBuCN)3)], that is, [Ru(CF3SO3){NCC(CH3)3}4(IMesH2)]+[CF3SO3]− (1), [Ru(CF3SO3){NCC(CH3)3}4(IMes)]+[CF3SO3]− (2), [RuCl{NCC(CH3)3}4(IMes)]+Cl− (3), [RuCl{NCC(CH3)3}4(IMesH2)+Cl−]/[RuCl2{NCC(CH3)3}3(IMesH2)] (4), and [Ru(NCO)2{NCC(CH3)3}3(IMesH2)] (5) (IMes=1,3‐dimesitylimidazol‐2‐ylidene, IMesH2=1,3‐dimesityl‐imidazolin‐2‐ylidene) have been synthesized and used as UV‐triggered precatalysts for the ring‐opening metathesis polymerization (ROMP) of different norborn‐2‐ene‐ and cis‐cyclooctene‐based monomers. The absorption maxima of complexes 1–5 were in the range of 245–255 nm and thus perfectly fit the emission band of the 254 nm UV source that was used for activation. Only the cationic RuII‐complexes based on ligands capable of forming μ2‐complexes such as 1 and 2 were found to be truly photolatent in ROMP. In contrast, complexes 3–5 could be activated by UV light; however, they also showed a low but significant ROMP activity in the absence of UV light. As evidenced by 1H and 13C NMR spectroscopy, the structure of the polymers obtained with either 1 or 2 are similar to those found in the corresponding polymers prepared by the action of [Ru(CF3SO3)2(IMesH2)(CH‐2‐(2‐PrO)‐C6H4)], which strongly suggest the formation of Ru‐based Grubbs‐type initiators in the course of the UV‐based activation process. Precatalysts that have the IMesH2 ligand showed significantly enhanced reactivity as compared with those based on the IMes ligand, which is in accordance with reports on the superior reactivity of IMesH2‐based Grubbs‐type catalysts compared with IMes‐based systems.
