Hot Paper: Coordination-Driven In Situ Self-Assembly Strategy for the Preparation of Metal–Organic-Framework Hybrid Membranes

Rong Zhang, Prof. Shulan Ji, Dr. Naixin Wang, Lin Wang, Prof. Guojun Zhang and Jian-Rong Li

Coordination-Driven In Situ Self-Assembly Strategy for the Preparation of Metal–Organic-Framework Hybrid MembranesMopping up the mess: A hybrid membrane composed of the metal–organic framework (MOF) ZIF-8 and poly(sodium 4-styrenesulfonate) was prepared by coordination-driven in situ self-assembly method. The MOF particles were well-dispersed in the polymer in the resulting stable membrane (see picture), which showed excellent performance in the nanofiltration and separation of dyes from water.

Hot Paper: Unprecedented Role of Hydronaphthoquinone Tautomers in Biosynthesis

Dr. Syed Masood Husain, Dr. Michael A. Schätzle, Dr. Steffen Lüdeke and Prof. Dr. Michael Müller

Unprecedented Role of Hydronaphthoquinone Tautomers in BiosynthesisBreaking the cycle: In studies on the reduction of 2-hydroxynaphthoquinones to the stable 1,4-diketo tautomeric form of hydronaphthoquinones and their further reduction by fungal tetrahydroxynaphthalene reductase, diketo tautomers emerge as true intermediates in biosynthesis. Their formation breaks the (redox) cycle, thus protecting the cell from stress-related redox events.

Hot Paper: A Fast Deposition-Crystallization Procedure for Highly Efficient Lead Iodide Perovskite Thin-Film Solar Cells

Manda Xiao, Dr. Fuzhi Huang, Wenchao Huang, Yasmina Dkhissi, Dr. Ye Zhu, Prof. Dr. Joanne Etheridge, Dr. Angus Gray-Weale, Prof. Dr. Udo Bach, Prof. Dr. Yi-Bing Cheng and Prof. Dr. Leone Spiccia

A Fast Deposition-Crystallization Procedure for Highly Efficient Lead Iodide Perovskite Thin-Film Solar CellsFast and thin: Flat, uniform thin films of CH3NH3PbI3 perovskites have been produced by a fast, one-step procedure involving spin-coating of a DMF solution of CH3NH3PbI3 and immediate exposure to chlorobenzene to induce crystallization. Planar heterojunction solar cells made with these films gave a maximum power conversion efficiency of 16.2 %.

Hot Paper: Local Transient Unfolding of Native State PAI-1 Associated with Serpin Metastability

Dr. Morten B. Trelle, Dr. Jeppe B. Madsen, Prof. Peter A. Andreasen and Prof. Dr. Thomas J. D. Jørgensen

Local Transient Unfolding of Native State PAI-1 Associated with Serpin MetastabilitySerpin proteins are prone to pathological conformational change, for instance by conversion to an inactive, so-called latent form. Using advanced hydrogen/deuterium-exchange mass spectrometry transient unfolding of a serpin is shown under native condition. Based on these observations, a new mechanism (see picture) is proposed.

VIP: Integrating Perovskite Solar Cells into a Flexible Fiber

Longbin Qiu, Jue Deng, Xin Lu, Zhibin Yang and Prof. Huisheng Peng

Integrating Perovskite Solar Cells into a Flexible FiberWearable perovskite solar cells with a fiber structure are synthesized by continuously winding an aligned carbon nanotube (CNT) sheet onto a stainless-steel wire; photoactive materials are incorporated in between them through a solution process. The fiber-shaped perovskite solar cell exhibits an energy conversion efficiency of 3.3 % and may be woven into electronic textiles.

Hot Paper: Plasmon-Induced Ammonia Synthesis through Nitrogen Photofixation with Visible Light Irradiation

Dr. Tomoya Oshikiri, Prof. Kosei Ueno and Prof. Hiroaki Misawa

Plasmon-Induced Ammonia Synthesis through Nitrogen Photofixation with Visible Light IrradiationSee the light of day: A plasmon-induced ammonia synthesis technique that responds to visible light and is based on a strontium titanate (SrTiO3) photoelectrode loaded with gold nanoparticles has been developed. It is deduced that plasmon-induced charge separation at the Au/SrTiO3 interface promotes oxidation in the anodic chamber and subsequent nitrogen reduction on the cathodic side.

Hot Paper: Selective Capture of Carbon Dioxide under Humid Conditions by Hydrophobic Chabazite-Type Zeolitic Imidazolate Frameworks

Nhung T. T. Nguyen, Dr. Hiroyasu Furukawa, Dr. Felipe Gándara, Dr. Hoang T. Nguyen, Kyle E. Cordova and Prof. Omar M. Yaghi

Selective Capture of Carbon Dioxide under Humid Conditions by Hydrophobic Chabazite-Type Zeolitic Imidazolate FrameworksWetting their appetite for CO2: Hydrophobic zeolitic imidazolate frameworks (ZIFs) with the chabazite (CHA) topology selectively capture CO2 from N2 in the presence of water. They thus overcome crucial challenges faced by many other porous materials for which even the smallest amount of water causes decomposition or decreases the materials’ ability to capture CO2.

VIP: Bonding Nature of Local Structural Motifs in Amorphous GeTe

Dipl.-Chem. Volker L. Deringer, Dr. Wei Zhang, Dr. Marck Lumeij, Dipl.-Chem. Stefan Maintz, Prof. Dr. Matthias Wuttig, Prof. Dr. Riccardo Mazzarello and Prof. Dr. Richard Dronskowski

Bonding Nature of Local Structural Motifs in Amorphous GeTeAmorphous—no problem! Analyzing a crystalline structure by breaking it down into local fragments and covalent bonds is a technique that chemists have long perfected. With new tools at hand, this chemical language can be extended to amorphous solid-state materials—in this case, to the phase-change memory alloy germanium telluride.

Angewandte Chemie 29/2014: Four Stars

Angewandte Chemie 29/2014: Four StarsIn this issue, S.-L. Suraru and F. Würthner review syntheses of functional naphthalene diimides. What strategies are the most promising? In a Minireview, K. A. Jørgensen et al. discuss asymmetric organocatalytic epoxidations. The Highlight deals with the preparation of CO2/diene copolymers (G. Fiorani and A. W. Kleij).

In the Communications section, M. J. Bojdys et al. present a two-dimensional semiconductor: triazine-based graphitic carbon nitride (see picture). M. Scheer et al. succeeded in the selective functionalization of P4 by metal-mediated C–P bond formation. Y. Cao et al. describe a gold-catalyzed hydrogenative coupling of nitroarenes to synthesize aromatic azo compounds, and J. W. Bode et al. show how to prepare potassium acyltrifluoroborates in just one step.

Hot Paper: High-Performance Hole-Extraction Layer of Sol–Gel-Processed NiO Nanocrystals for Inverted Planar Perovskite Solar Cells

Zonglong Zhu, Yang Bai, Teng Zhang, Dr. Zhike Liu, Dr. Xia Long, Zhanhua Wei, Zilong Wang, Lixia Zhang, Prof. Jiannong Wang, Prof. Feng Yan and Prof. Shihe Yang

High-Performance Hole-Extraction Layer of Sol–Gel-Processed NiO Nanocrystals for Inverted Planar Perovskite Solar CellsThe advantages are crystal clear: A transparent layer of NiO nanocrystals fabricated by a simple sol–gel processing method acted as an efficient hole-transport layer in an inverted perovskite solar cell. With the NiO film (see picture), a cell efficiency of 9.11 % was observed: by far the highest for a planar perovskite solar cell based on an inorganic hole-extraction layer.

Hot Paper: Synthesis of (+)-Discodermolide by Catalytic Stereoselective Borylation Reactions

Zhiyong Yu, Robert J. Ely and Prof. James P. Morken

Synthesis of (+)-Discodermolide by Catalytic Stereoselective Borylation ReactionsBorylation-based synthesis: The development of a strategy for stereocontrol in catalytic diene hydroboration enables the synthesis of a critical building block for the assembly of (+)-discodermolide. Combined with asymmetric catalytic diboration, hydroformylation, and borylative aldehyde–diene coupling reactions, (+)-discodermolide could then be prepared from simple hydrocarbon-based building blocks.
