Non-Aqueous Sol–Gel Synthesis of Ultra Small Persistent Luminescence Nanoparticles for Near-Infrared In Vivo Imaging

Non-Aqueous Sol–Gel Synthesis of Ultra Small Persistent Luminescence Nanoparticles for Near-Infrared In Vivo ImagingLuminescing with persistence: Ultra-small ZnGa2O4:Cr3+ nanoparticles (6 nm) that exhibit near-infrared persistent luminescence are synthesized by using a non-aqueous sol–gel method. The nanoparticles are shown to be useful optical nanotools as they emit without the need for continuous in situ excitation and they avoid tissue autofluorescence.

Computational Mechanistic Elucidation of Intramolecular Aminoalkene Hydroamination Catalysed by Iminoanilide Alkaline-Earth Compounds

Dr. Sven Tobisch

Computational Mechanistic Elucidation of Intramolecular Aminoalkene Hydroamination Catalysed by Iminoanilide Alkaline-Earth CompoundsComputational investigation of the diverse pathway of iminoanilide alkaline-earth (Ae) silylamido compound-catalysed aminoalkene hydroamination provides compelling evidence for the operation of a stepwise {N^N}Ae[BOND]Namido σ-bond insertive mechanism that involves a rapid, reversible migratory olefin 1,2-insertion step linked to a less facile, irreversible Ae[BOND]Calkyl σ-bond aminolysis step.

Oxidized Carbon Nitrides: Water-Dispersible, Atomically Thin Carbon Nitride-Based Nanodots and Their Performances as Bioimaging Probes

Junghoon Oh, Ran Ji Yoo, Seung Yeon Kim, Yong Jin Lee, Prof. Dong Wook Kim and Prof. Sungjin Park

Oxidized Carbon Nitrides: Water-Dispersible, Atomically Thin Carbon Nitride-Based Nanodots and Their Performances as Bioimaging ProbesOCN view: Water-dispersible, atomically thin, and small carbon nitride nanodots were produced using the chemical oxidation of graphitic C3N4. The 2D C3N4 nanodots were successfully exfoliated as individual single layers; their lateral dimension was several tens of nanometers. They showed strong photoluminescence in the visible region as well as excellent performances as cell-imaging probes in an in vitro study using confocal fluorescence microscopy.

Titanium-Catalyzed Reductive Umpolung Reactions with a Metal-Free Terminal Reducing Agent

Georg Frey, J. Niklas Hausmann and Dr. Jan Streuff

Titanium-Catalyzed Reductive Umpolung Reactions with a Metal-Free Terminal Reducing AgentReplacing zinc: A protocol for titanium(III)-catalyzed reductive umpolung reactions is presented that enables the title reactions in the presence of an N,N′-disilylated tetramethyldihydropyrazine as an organic sacrificial reducing agent. It is successfully applied to carbonyl–nitrile, enone–acrylonitrile and pinacol coupling reactions. A remarkable effect of the titanocene counterion renders titanocene diiodide a superior catalyst.

Reactivity and Operational Stability of N-Tailed TAMLs through Kinetic Studies of the Catalyzed Oxidation of Orange II by H2O2: Synthesis and X-ray Structure of an N-Phenyl TAML

Genoa R. Warner, Matthew R. Mills, Clarissa Enslin, Shantanu Pattanayak, Chakadola Panda, Tamas Kumar Panda, Prof. Sayam Sen Gupta, Prof. Alexander D. Ryabov and Prof. Terrence J. Collins

Reactivity and Operational Stability of N-Tailed TAMLs through Kinetic Studies of the Catalyzed Oxidation of Orange II by H2O2: Synthesis and X-ray Structure of an N-Phenyl TAMLN-Tailed TAMLs in water: Iron–TAML (tetraamido macrocyclic ligand) activators with N-methyl tail adopt a similar mechanism of oxidative catalysis and display comparable reactivity in water as their earlier prototypes despite their compactness (see scheme).
