A Pre‐organised Truxene Platform for Phosphorescent [Ru(bpy)2] and [Os(bpy)2] Metal Centres: A Clear‐Cut Switch from Förster‐ to Dexter‐Type Energy‐Transfer Mechanism
Authors: Diring Stéphane , Ziessel Raymond , Barigelletti Francesco , Barbieri Andrea , Ventura Barbara 
Published: June 2010

AbstractWe report on the synthesis, optical properties and energy‐transfer features of a series of transition‐metal‐containing complexes and dyads, based on a pre‐organised truxene scaffold. In this series, the [Ru(bpy)3]2+ and [Os(bpy)3]2+ photoactive terminals are coupled to the bridging aromatic truxene core through rigid ethynyl linkers. The photoinduced energy‐transfer processes taking place from the Ru‐ to the Os‐based levels, and from the truxene bridging ligand to the terminal‐metal chromophores are studied and the pathways and mechanisms are discussed. The photoinduced energy‐transfer process observed in the dyad proceeds rapidly through: i) an efficient 1L→1Os direct energy transfer followed by intersystem crossing to 3Os, and ii) a fast 1L→1Ru energy‐transfer step and subsequent intersystem crossing to 3Ru followed by a 3Ru→3Os energy‐transfer process. The first 1L→1Os and 1L→1Ru steps are controlled by a dipole–dipole interaction (Förster mechanism), whereas the subsequent 3Ru→3Os step proceeds by means of a long‐range (≈24 Å) through‐bond mediated Dexter mechanism, facilitated by the conjugation along the bpy‐truxene‐bpy molecular axis.
Cyclodextrin‐Based Bimodal Fluorescence/MRI Contrast Agents: An Efficient Approach to Cellular Imaging
Authors: Kotková Zuzana , Kotek Jan , Jirák Daniel , Jendelová Pavla , Herynek Vít , Berková Zuzana , Hermann Petr , Lukeš Ivan 
Published: June 2010

AbstractA novel bimodal fluorescence/MRI probe based on a cyclodextrin scaffold has been synthesized and characterized. The final agent employs the fluorescein (F) functionality as a fluorescence marker and the GdIII complex of a macrocyclic DOTA‐based ligand (GdL) having one aminobenzyl‐phosphinic acid pendant arm as an MRI probe, and has a statistical composition of (GdL)6.9‐F0.1‐β‐CD. Slow rotational dynamics (governed by a very rigid cyclodextrin scaffold) combined with fast water exchange (ensured by the chosen macrocyclic ligand) resulted in a high relaxivity of ∼22 s−1 mM−1 per GdIII or ∼150 s−1 mM−1 per molecule of the final conjugate (20 MHz, 25 °C). In vitro labelling of pancreatic islets (PIs) and rat mesenchymal stem cells has been successfully performed. The agent is not cytotoxic and is easily internalized into cells. The labelled cells can be visualized by MRI, as proved by the detection of individual labelled PIs. A fluorescence study performed on mesenchymal stem cells showed that the agent stays in the intracellular space for a long time.
Thermo‐ and Acid‐Responsive Photochromic Spironaphthoxazine‐Containing Organogelators

Published: June 2010

AbstractA series of photochromic spironaphthoxazine derivatives has been designed, synthesized, and characterized by using 1H NMR spectroscopy, FAB mass spectrometry, and elemental analysis. Their photophysical and photochromic behavior have been investigated. Two of the compounds (G12‐en‐SA‐SO and G16‐en‐SA‐SO) have been shown to be capable of forming stable thermoreversible organogels in organic solvents, tested by the “stable‐to‐inversion of a test tube” method. Addition of p‐toluenesulfonic acid was found to induce the formation of stable organogels at concentrations below that of the critical gelation concentration (c.g.c.), with a concomitant change in color from colorless to purple. Transmission electron microscopy and scanning electron microscopy of the xerogels showed typical fibrous structures in the micrometer scale. The activation parameters for the bleaching reaction of G8‐en‐SA‐SO in the solution state and G16‐en‐SA‐SO in the gel state have been determined in ethanol through kinetic studies at various temperatures. The results showed that the rate of the bleaching reaction in the gel state was much slower than that in the solution state.
Mechanistic Insights into the One‐Pot Synthesis of Propargylamines from Terminal Alkynes and Amines in Chlorinated Solvents Catalyzed by Gold Compounds and Nanoparticles
Authors: Aguilar David , Contel Maria , Urriolabeitia Esteban P. 
Published: June 2010

AbstractPropargylamines can be obtained from secondary amines and terminal alkynes in chlorinated solvents by a three‐ and two‐component synthesis catalyzed by gold compounds and nanoparticles (Au‐NP) under mild conditions. The use of dichloromethane allows for the activation of two CCl bonds and a clean transfer of the methylene fragment to the final product. The scope of the reaction as well as the influence of different gold(III) cycloaurated complexes and salts has been investigated. The involvement of gold nanoparticles generated in situ in the process is discussed and a plausible reaction mechanism is proposed on the basis of the data obtained.
Iron(III)‐Catalyzed Cyclization of Alkynyl Aldehyde Acetals: Experimental and Computational Studies

Published: June 2010

AbstractFeCl3⋅6 H2O‐ and FeBr3‐catalyzed Prins cyclization/halogenation of alkynyl aldehyde acetals has been realized with acetyl chloride or bromide as halogen source in dichloromethane to afford 2‐(1‐halobenzylidene or alkylidene)‐substituted five‐membered carbo‐ and heterocycles, and thus provides an alternative route for vinylic CCl and CBr bond formation. Five‐ to eight‐membered cyclic enones were efficiently synthesized by FeCl3⋅6 H2O‐catalyzed intramolecular cyclization of alkynyl aldehyde acetals in acetone under mild conditions. An oxocarbonium species generated in situ is proposed to initiate the reaction, and the target products are formed via vinylogous carbenium cation and oxete intermediates according to DFT calculations. Intermolecular reactions of alkynes and aldehyde acetals were also investigated with 20–40 mol % FeCl3⋅6 H2O catalyst, and produced α,β‐unsaturated enones and chlorinated indene derivatives. The present protocol has applications in the synthesis of carbo‐, oxa‐ and azacycles.
Fullerene Derivatives That Bear Aliphatic Chains as Unusual Surfactants: Hierarchical Self‐Organization, Diverse Morphologies, and Functions
Authors: Asanuma Hidehiko , Li Hongguang , Nakanishi Takashi , Möhwald Helmuth 
Published: June 2010

AbstractConventionally, amphiphiles are composed of hydrophobic and hydrophilic units. They are able to exhibit a wide variety of structures depending on the environment. Such features have been applied in supramolecular chemistry, by which apolar and polar groups are implemented in the molecular design. Here we present an attractive approach to introduce unique amphiphilicity. Relatively simple fullerene (C60) derivatives that bear long aliphatic chains behave as uncommon surfactants in organic media. Although two hydrophobic units are used to assemble the derivatives, slight differences in their polarity and chemical nature may make them incompatible and thus arrange them in microphase‐separated mesostructures as lamellar ones. These assemblies are maintained by relatively weak forces, π–π interactions among C60 moieties and van der Waals forces between alkyl chains. Therefore, the derivatives can undergo “supramolecular polymorphism” by which different supramolecular assemblies arise by changing the conditions of assembly. A simple modification in their substituent motif of derivatives influences the intermolecular interactions and provides a wide variety of supramolecular materials.
