New Multichromophoric Ligand for Light Harvesting

New Multichromophoric Ligand for Light Harvesting

Light-harvesting antennae are of great importance for the development of efficient solar cells. Multichromophoric systems capable of harvesting light are of interest as they can be used in multicomponent systems in which the different chromophores are in close contact to favor energy and/or electron transfer, so that the excitation energy can be funneled to a specific acceptor. If one of these chromophores is also a good ligand for metal ions, new interesting properties can arise in a supramolecular system, such as control of the energy/electron transfer processes by changing the metal ion or the ability to generate supramolecular architectures and coordination polymers. To find out more about this subject read the paper by Marc Gingras, Aix-Marseille Université, France, Giacomo Bergamini, University of Bologna, Italy, and co-workers

  1. Regioselective Deiodination of Iodothyronamines, Endogenous Thyroid Hormone Derivatives, by Deiodinase Mimics

    Santanu Mondal and Prof. Dr. Govindasamy Mugesh

    Article first published online: 24 JUL 2014 | DOI: 10.1002/chem.201403248

    Modelling what you want: Whereas 3,3′,5-triiodothyronine (T3) forms a dimeric structure in solution through hydrogen bonding and weak intermolecular I⋅⋅⋅I halogen bonding, such interactions are also observed for 3,3′,5-triiodothyronamine (T3 AM; see figure). The attack of a selenol group at the iodine atom is, therefore, more favored for the dimeric T3 than the monomeric T3 AM.

  2. Synthesis, Structure, and Reactivity of Diazene Adducts: Isolation of iso-Diazene Stabilized as a Borane Adduct

    Dipl.-Chem. Fabian Reiß, Prof. Dr. Axel Schulz  and Dr. Alexander Villinger

    Article first published online: 24 JUL 2014 | DOI: 10.1002/chem.201402921

    Iso-lated! Diazenes of the type R1[BOND]N[DOUBLE BOND]N[BOND]R2 (R1=R2=SiMe3, Ph; R1=Me3Si, R2=Ph; see figure) were shown to form stable GaCl3 and B(C6F5)3 adducts depending on the reaction conditions, temperature, and UV light.

  3. Amyloid Transition of Ubiquitin on Silver Nanoparticles Produced by Pulsed Laser Ablation in Liquid as a Function of Stabilizer and Single-Point Mutations

    Dr. Vincenzo Mangini, Dr. Marcella Dell'Aglio, Dr. Angelo De Stradis, Dr. Alessandro De Giacomo, Dr. Olga De Pascale, Prof. Giovanni Natile and Prof. Fabio Arnesano

    Article first published online: 24 JUL 2014 | DOI: 10.1002/chem.201402934

    Thumbnail image of graphical abstract

    Human ubiquitin forms amyloids on the surface of silver nanoparticles produced by laser ablation, which induce clustering of the nanoparticles and thioflavin T fluorescence. In the presence of sodium citrate as a stabilizer, ubiquitin only forms a protein corona. A single mutation (Glu16Val) at one edge β strand of the protein can deeply influence the amyloid transition (see figure).

  4. Directly Decoupled Diffusion-Ordered NMR Spectroscopy for the Analysis of Compound Mixtures

    Simon Glanzer and Prof. Dr. Klaus Zangger

    Article first published online: 24 JUL 2014 | DOI: 10.1002/chem.201402920

    Thumbnail image of graphical abstract

    Hardcore NMR: Diffusion-ordered spectroscopy (DOSY) is often used for the separation of signals based on their self-diffusion coefficient. To overcome problems arising for overlapped signals, an approach that allows the acquisition of pure-shift DOSY spectra without the introduction of an additional decoupling dimension, by direct decoupling during acquisition, is presented (see figure).

  5. Ruthenium-Catalyzed Cycloadditions of 1-Haloalkynes with Nitrile Oxides and Organic Azides: Synthesis of 4-Haloisoxazoles and 5-Halotriazoles

    James S. Oakdale, Dr. Rakesh K. Sit and Prof. Dr. Valery V. Fokin

    Article first published online: 24 JUL 2014 | DOI: 10.1002/chem.201402559

    Thumbnail image of graphical abstract

    1-Haloalkyne cycloadditions: Ruthenium(II)-catalyzed ([CpRuCl(cod)], 1,5-cod=cyclooctadiene, Cp=cyclopentadienyl; see scheme) azide–alkyne and nitrile oxide–alkyne cycloadditions provide a convenient and regioselective means for the preparation of 5-halo-1,2,3-triazoles and 4-haloisoxazoles from electron-deficient 1-chloro-, 1-bromo-, and 1-iodoalkynes.
