Published: January 2016

AbstractUnderstanding the driving forces controlling crystallization is essential for the efficient synthesis and design of new materials, particularly metal–organic frameworks (MOFs), where mild solvothermal synthesis often allows access to various phases from the same reagents. Using high‐energy in situ synchrotron X‐ray powder diffraction, we monitor the crystallization of lithium tartrate MOFs, observing the successive crystallization and dissolution of three competing phases in one reaction. By determining rate constants and activation energies, we fully quantify the reaction energy landscape, gaining important predictive power for the choice of reaction conditions. Different reaction rates are explained by the structural relationships between the products and the reactants; larger changes in conformation result in higher activation energies. The methods we demonstrate can easily be applied to other materials, opening the door to a greater understanding of crystallization in general.

Published: January 2016

AbstractThe ground state electronic structure of copper corroles has been a topic of debate and revision since the advent of corrole chemistry. Computational studies formulate neutral Cu corroles with an antiferromagnetically coupled CuII corrole radical cation ground state. X‐ray photoelectron spectroscopy, EPR, and magnetometry support this assignment. For comparison, CuII isocorrole and [TBA][Cu(CF3)4] were studied as authentic CuII and CuIII samples, respectively. In addition, the one‐electron reduction and one‐electron oxidation processes are both ligand‐based, demonstrating that the CuII centre is retained in these derivatives. These observations underscore ligand non‐innocence in copper corrole complexes.
Konformativer Schlupf bestimmt die Rotationsfrequenz in Fünf‐Komponenten‐Nanorotoren
Authors: Samanta Soumen K. , Rana Anup , Schmittel Michael 
Published: January 2016

AbstractMehrere Fünf‐Komponenten‐Nanorotoren ROT‐3 mit unterschiedlicher Geschwindigkeit wurden durch Zugabe von als Bremsklötzen dienenden Phenanthrolin‐Bausteinen unterschiedlicher lateraler Ausdehnung aus dem Vier‐Komponenten‐Nanorotor ROT‐2 hergestellt. Die Bremsklötze interferieren mit dem 180°‐Rotor und führen zu einer Absenkung der Rotationsfrequenz von 97 auf 5 kHz. Die Auswirkung der ebenfalls rotierenden Bremsklötze auf die Rotationsfrequenz in ROT‐3 wird durch das nanomechanische Modell “konformativer Schlupf” präzise vorausgesagt. Für die Quantifizierung wird die Wechselwirkung der Bremsklötze mit der Trajektorie des Hauptrotators evaluiert, wozu die Zahl der interferierenden und der nichtinterferierenden Konformationen mit PM6 berechnet wird.

AbstractAlthough persistent room‐temperature phosphorescence (RTP) emission has been observed for a few pure crystalline organic molecules, there is no consistent mechanism and no universal design strategy for organic persistent RTP (pRTP) materials. A new mechanism for pRTP is presented, based on combining the advantages of different excited‐state configurations in coupled intermolecular units, which may be applicable to a wide range of organic molecules. By following this mechanism, we have developed a successful design strategy to obtain bright pRTP by utilizing a heavy halogen atom to further increase the intersystem crossing rate of the coupled units. RTP with a remarkably long lifetime of 0.28 s and a very high quantum efficiency of 5 % was thus obtained under ambient conditions. This strategy represents an important step in the understanding of organic pRTP emission.

End‐to‐End Self‐Assembly of Semiconductor Nanorods in Water by Using an Amphiphilic Surface Design
Authors: Taniguchi Yuki , Takishita Takao , Kawai Tsuyoshi , Nakashima Takuya 
Published: January 2016

AbstractOne‐dimensional (1D) self‐assemblies of nanocrystals are of interest because of their vectorial and polymer‐like dynamic properties. Herein, we report a simple method to prepare elongated assemblies of semiconductor nanorods (NRs) through end‐to‐end self‐assembly. Short‐chained water‐soluble thiols were employed as surface ligands for CdSe NRs having a wurtzite crystal structure. The site‐specific capping of NRs with these ligands rendered the surface of the NRs amphiphilic. The amphiphilic CdSe NRs self‐assembled to form elongated wires by end‐to‐end attachment driven by the hydrophobic effect operating between uncapped NR ends. The end‐to‐end assembly technique was further applied to CdS NRs and CdSe tetrapods (TPs) with a wurtzite structure.

Published: January 2016

AbstractThis study describes, for the first time, the generation of a SF5‐substituted ester enolate from benzyl SF5‐acetate under soft enolization conditions, which in turn participates in aldol addition reactions in high yield. The reaction was applied in the synthesis of 3‐SF5‐quinolin‐2‐ones, 3‐SF5‐quinolines, and 3‐SF5‐pyridin‐2‐ones, none of which have previously been reported. To provide guidelines for their use in drug discovery, the physicochemical properties of these building blocks were determined and compared with those of their CF3‐ and t‐Bu‐analogues.

Published: January 2016

AbstractA facile, reproducible, and scalable method was explored to construct uniform Au@poly(acrylic acid) (PAA) Janus nanoparticles (JNPs). The as‐prepared JNPs were used as templates to preferentially grow a mesoporous silica (mSiO2) shell and Au branches separately modified with methoxy‐poly(ethylene glycol)‐thiol (PEG) to improve their stability, and lactobionic acid (LA) for tumor‐specific targeting. The obtained octopus‐type PEG‐Au‐PAA/mSiO2‐LA Janus NPs (PEG‐OJNP‐LA) possess pH and NIR dual‐responsive release properties. Moreover, DOX‐loaded PEG‐OJNP‐LA, upon 808 nm NIR light irradiation, exhibit obviously higher toxicity at the cellular and animal levels compared with chemotherapy or photothermal therapy alone, indicating the PEG‐OJNP‐LA could be utilized as a multifunctional nanoplatform for in vitro and in vivo actively‐targeted and chemo‐photothermal cancer therapy.
Temporal Control of Gelation and Polymerization Fronts Driven by an Autocatalytic Enzyme Reaction
Authors: Jee Elizabeth , Bánsági Tamás , Taylor Annette F. , Pojman John A. 
Published: January 2016

AbstractChemical systems that remain kinetically dormant until activated have numerous applications in materials science. Herein we present a method for the control of gelation that exploits an inbuilt switch: the increase in pH after an induction period in the urease‐catalyzed hydrolysis of urea was used to trigger the base‐catalyzed Michael addition of a water‐soluble trithiol to a polyethylene glycol diacrylate. The time to gelation (minutes to hours) was either preset through the initial concentrations or the reaction was initiated locally by a base, thus resulting in polymerization fronts that converted the mixture from a liquid into a gel (ca. 0.1 mm min−1). The rate of hydrolytic degradation of the hydrogel depended on the initial concentrations, thus resulting in a gel lifetime of hours to months. In this way, temporal programming of gelation was possible under mild conditions by using the output of an autocatalytic enzyme reaction to drive both the polymerization and subsequent degradation of a hydrogel.
Spin‐Selective Generation of Triplet Nitrenes: Olefin Aziridination through Visible‐Light Photosensitization of Azidoformates

Published: January 2016

AbstractAzidoformates are interesting potential nitrene precursors, but their direct photochemical activation can result in competitive formation of aziridination and allylic amination products. Herein, we show that visible‐light‐activated transition‐metal complexes can be triplet sensitizers that selectively produce aziridines through the spin‐selective photogeneration of triplet nitrenes from azidoformates. This approach enables the aziridination of a wide range of alkenes and the formal oxyamination of enol ethers using the alkene as the limiting reagent. Preparative‐scale aziridinations can be easily achieved under continuous‐flow conditions.
Gelled Complex Fluids: Combining Unique Structures with Mechanical Stability
Authors: Stubenrauch Cosima , Gießelmann Frank 
Published: January 2016

AbstractGelled complex fluids are soft materials in which the microstructure of the complex fluid is combined with the mechanical stability of a gel. To obtain a gelled complex fluid one either adds a gelator to a complex fluid or replaces the solvent in a gel by a complex fluid. The most prominent example of a “natural” gelled complex fluid is the cell. There are various strategies by which one can form a gelled complex fluid; one such strategy is orthogonal self‐assembly, that is, the independent but simultaneous formation of two coexisting self‐assembled structures within one system. The aim of this Review is to describe the structure and potential applications of various man‐made gelled complex fluids and to clarify whether or not the respective system is formed by orthogonal self‐assembly.

Published: January 2016

AbstractActive sites in carbon‐catalyzed phosgene synthesis from gaseous CO and Cl2 have been identified using C60 fullerene as a model catalyst. The carbon atoms distorted from sp2 coordination in non‐planar carbon units are concluded to generate active Cl2. Experiments and density functional theory calculations indicate the formation of a surface‐bound [C60⋅⋅⋅Cl2] chlorine species with radical character as key intermediate during phosgene formation. It reacts rapidly with physisorbed CO in a two‐step Eley–Rideal‐type mechanism.

Published: January 2016

AbstractA heterogeneous, inexpensive, and environmentally friendly graphene oxide catalytic system for the C−H bond arylation of benzene enables the formation of biaryl compounds in the presence of aryl iodides. The oxygen functional groups in these graphene oxide sheets and the addition of KOtBu are essential for the observed catalytic activity. Reactions with various model compounds and DFT calculations confirmed that these negatively charged oxygen atoms promote the overall transformation by stabilizing and activating K+ ions, which in turns facilitates the activation of the C−I bond. However, the graphene π system also greatly facilitates the overall reaction as the aromatic coupling partners are easily adsorbed.
Oxidative Coupling of Aryl Boron Reagents with sp3‐Carbon Nucleophiles: The Enolate Chan–Evans–Lam Reaction
Authors: Moon Patrick J. , Halperin Heather M. , Lundgren Rylan J. 
Published: January 2016

AbstractReported is a versatile new oxidative method for the arylation of activated methylene species. Under mild reaction conditions (RT to 40 °C), Cu(OTf)2 mediates the selective coupling of functionalized aryl boron species with a variety of stabilized sp3‐nucleophiles. Tertiary malonates and amido esters can be employed as substrates to generate quaternary centers. Complementing either traditional cross‐coupling or SNAr protocols, the transformation is chemoselective in the presence of halogen electrophiles, including aryl bromides and iodides. Substrates bearing amide, sulfonyl, and phosphonyl groups, which are not amenable to coupling under mild Hurtley‐type conditions, are suitable reaction partners.

Published: January 2016

AbstractSelf‐assembly driven by crown ether complexation of zinc phthalocyanines equipped with one 18‐crown‐6 moiety and fullerenes bearing an ammonium head group afforded a novel donor–acceptor hybrid. In reference experiments, fullerenes containing a Boc‐protected amine functionality have been probed. The circumvention of zinc phthalocyanine aggregation is important for the self‐assembly, which required the addition of pyridine. From absorption and fluorescence titration assays, which provided sound and unambiguous evidence for mutual interactions between the electron donor and the electron acceptor within the hybrids, association constants in the order of 8.0×105 m−1 have been derived. The aforementioned is based on 1:1 stoichiometries, which have been independently confirmed by Job's plot measurements. In the excited state, which has been examined by transient absorption experiments, intermolecular charge separation evolves from the photoexcited zinc phthalocyanine to the fullerene subunit and leads to short‐lived charge‐separated states. Interestingly, photoexcitation of zinc phthalocyanine dimers/aggregates can also be followed by an intermolecular charge separation between vicinal phthalocyanines. These multicomponent supramolecular ensembles have also been shown by in‐depth electrospray ionization mass spectrometry (ESI‐MS) studies, giving rise to the formation and detection of a variety of non‐covalently linked species.
S‐Trifluoromethylation of Thiols by Hypervalent Iodine Reagents: A Joint Experimental and Computational Study

Published: January 2016

AbstractThe radical trifluoromethylation of thiophenol in condensed phase applying reagent 1 (3,3‐dimethyl‐1‐(trifluoromethyl)‐1λ3,2‐benziodoxol) has been examined by both theoretical and experimental methodologies. On the basis of ab initio molecular dynamics and metadynamics we show that radical reaction mechanisms favourably compete with polar ones involving the S‐centred nucleophile thiophenol, their free energies of activation, ΔF≠, lying between 9 and 15 kcal mol−1. We further show that the origin of the proton activating the reagent is important. Hammett plot analysis reveals intramolecular protonation of 1, thus generating negative charge on the sulfur atom in the rate‐determining step. The formation of a CF3 radical can be thermally induced by internal dissociative electron transfer, its activation energy, ΔF≠, amounting to as little as 10.8 and 2.8 kcal mol−1 for reagent 1 and its protonated form 2, respectively. The reduction of the iodine atom by thiophenol occurs either subsequently or in a concerted fashion.
