All‐Fullerene Electron Donor–Acceptor Conjugates

Published: 22 March 2019

Author(s): Marta Izquierdo, Benedikt Platzer, Anton J. Stasyuk, Olga A. Stasyuk, Alexander A. Voityuk, Sergio Cuesta, Miquel Solà, Dirk M. Guldi, Nazario Martín

Abstract The synthesis and characterization of a covalent all‐fullerene C60‐Lu3N@Ih‐C80 electron donor–acceptor conjugate has been realized by sequential 1,3‐dipolar cycloaddition reactions of azomethine ylides on Lu3N@Ih‐C80 and C60. To the best of our knowledge, this is the first time that two fullerenes behaving as both electron donor (Lu3N@Ih‐C80) and acceptor (C60) are forming an electroactive dumbbell. DFT calculations reveal up to 16 diastereomeric pairs, that is, 8 with syn and 8 with...

Polymer Dispersity Control by Organocatalyzed Living Radical Polymerization

Published: 22 March 2019

Author(s): Xu Liu, Chen‐Gang Wang, Atsushi Goto

Abstract Molecular weight distribution of polymers, termed dispersity (Đ), is a fundamental parameter for determining polymer material properties. This paper reports a novel approach for controlling Đ by exploiting a temperature‐selective radical generation in organocatalyzed living radical polymerization. The polymers with tailored Đ were synthesized in a batch system without the assistance of an external pump. A unique aspect of this approach is that Đ was tuneable from 1.11 to 1.50 in any...

Air‐Blowing‐Assisted Coaxial Electrospinning toward High Productivity of Core/Sheath and Hollow Fibers

Published: 22 March 2019

Author(s): Gaigai Duan, Andreas Greiner

Abstract Coaxial electrospinning is an attractive technology to produce core/sheath and hollow fibers. However, until now, the relatively low productivity has limited its broad applications. In this work, coaxial electrospinning with air‐blowing‐assistance is applied to improve the productivity of core/sheath and hollow fibers. Different core and shell materials are used for this electrospinning. The flow rate and air‐blowing rate during electrospinning are optimized. SEM and TEM are used to...

Fluorescent Triazole Urea Activity‐Based Probes for the Single‐Cell Phenotypic Characterization of Staphylococcus aureus

Published: 22 March 2019

Author(s): Linhai Chen, Laura J. Keller, Edward Cordasco, Matthew Bogyo, Christian S. Lentz

Abstract Phenotypically distinct cellular (sub)populations are clinically relevant for the virulence and antibiotic resistance of a bacterial pathogen, but functionally different cells are usually indistinguishable from each other. Herein, we introduce fluorescent activity‐based probes as chemical tools for the single‐cell phenotypic characterization of enzyme activity levels in Staphylococcus aureus. We screened a 1,2,3‐triazole urea library to identify selective inhibitors of...

The Generation of Difluoroketenimine and Its Application in the Synthesis of α,α‐Difluoro‐β‐amino Amides

Published: 22 March 2019

Author(s): Rui Zhang, Zhikun Zhang, Qi Zhou, Lefei Yu, Jianbo Wang

Abstract Fluorine‐containing β‐amino acids and their derivatives have attracted significant attention due to their importance in life sciences. Herein the previously unknown difluoroketenimine, the analogue of the elusive difluoroketene, has been generated by the reaction of difluorocarbene and isocyanide, which further undergoes [2+2] cycloaddition with imine. The three‐component reaction affords α,α‐difluoro‐β‐amino amides in good yields. Mechanistic studies reveal the unique properties of...

Ga2O3/TiO2 semiconductors free of noble metals for the photocatalytic hydrogen production in a water/methanol mixture

Published: 22 March 2019

Author(s): Michelle Navarrete, Sandra Cipagauta‐Díaz, Ricardo Gómez

Abstract Background Hydrogen gas (H2) has been identified as a potential energy source to reduce the dependence on fossil fuels. Titanium dioxide (TiO2) semiconductor has been widely used in photocatalysis. Doping of different semiconductor oxides into TiO2 has been documented to enhance its photocatalytic activity. In the present work, β‐Ga2O3/TiO2 (TG) photocatalysts for H2 production by water/methanol mixture decomposition have been synthesized by the sol–gel method varying the β‐Ga2O3...

Structural Transformation in Metal–Organic Frameworks for Reversible Binding of Oxygen

Published: 22 March 2019

Author(s): Jin‐Yue Zeng, Xiao‐Shuang Wang, Yong‐Dan Qi, Yun Yu, Xuan Zeng, Xian‐Zheng Zhang

Abstract Polycyclic aromatic derivatives can trap 1O2 to form endoperoxides (EPOs) for O2 storage and as sources of reactive oxygen species. However, these materials suffer from structural amorphism, which limit both practical applications and fundamental studies on their structural optimization for O2 capture and release. Metal–organic frameworks (MOFs) offer advantages in O2 binding, such as clear structure–performance relationships and precise controllability. Herein, we report the...

Synthetic Exploration of α‐Diazo γ‐Butyrolactams

Published: 22 March 2019

Author(s): Daniil Zhukovsky, Dmitry Dar'in, Grigory Kantin, Mikhail Krasavin

DIazo transfer reaction onto γ‐butyrolactams (activated by α‐ethyloxalylation) gave rare α‐diazo γ‐butyrolactams. Decomposition of the latter by Rh2(OAc)4 in the presence of alcohols and water gave products of O–H insertion of the respective metal‐cabene species. Silver triflate (1 mol‐%) was found to convert the γ‐butyrolactams investigated into 1,5‐dihydro‐2H‐pyrrol‐2‐ones which represent versatile building blocks. Particular instability was noted for α‐diazo γ‐butyrolactams bearing alkyl or...

Guests Like Gear Levers: Donor Binding to Coordinatively Unsaturated Metal Sites in MIL‐101 Controls the Linker′s Rotation

Published: 22 March 2019

Author(s): Alexander E. Khudozhitkov, Sergey S. Arzumanov, Daniil I. Kolokolov, Oxana A. Kholdeeva, Dieter Freude, Alexander G. Stepanov

Abstract We present investigation of the effect of electron‐donor guests on framework mobility in the metal–organic framework (MOF) MIL‐101(Cr) monitored by solid state 2H NMR spectroscopy. In a guest‐free material, the mobile phenylene fragments of the terephthalate (TP) linkers populate two fractions with notably different kinetic parameters for torsional motion. Two fractions of rotational motion are indicative of non‐equivalence of TP linker binding to the Cr3O trimer, the primary building...

Ambipolar Discotic Liquid Crystals Built Around Platinum Diimine‐Dithiolene Cores

Published: 22 March 2019

Author(s): Franck Camerel, Grégory Albert, Frédéric Barrière, Corinne Lagrost, Marc Fourmigué, Olivier Jeannin

Abstract Platinum diimine dithiolene complexes bearing mesogenic groups on one or both ligands have been prepared through an original ligand metathesis reaction to introduce the dithiolene ligand. The neutral diimine ligands, the intermediate platinum dichloride diimine complexes, and the target compounds were characterized by a combination of electronic (electrochemistry, absorption and emission spectroscopy, DFT calculations) and structural (SAXS, DSC) tools. Several novel liquid crystalline...
