A Tool for the Import of Natural and Unnatural Nucleoside Triphosphates into Bacteria

17-Jan-2018 | Aaron W. Feldman; Emil C. Fischer; Michael P. Ledbetter; Jen-Yu Liao; John C. Chaput; Floyd E. Romesberg, Journal of the American Chemical Society, 2018

Nucleoside triphosphates play a central role in biology, but efforts to study these roles have proven difficult because the levels of triphosphates are tightly regulated in a cell and because individual triphosphates can be difficult to label or modify. In addition, many synthetic biology efforts ...

Control of Amphiphile Self-Assembly via Bioinspired Metal Ion Coordination

17-Jan-2018 | Abigail S. Knight; Josefin Larsson; Jing M. Ren; Raghida Bou Zerdan; Shay Seguin; Remy Vrahas; Jianfang Liu; Gang Re ..., Journal of the American Chemical Society, 2018

Inspired by marine siderophores that exhibit a morphological shift upon metal coordination, hybrid peptide–polymer conjugates that assemble into different morphologies based on the nature of the metal ion coordination have been designed. Coupling of a peptide chelator, hexahistidine, with ...

Alanine-Based Chiral Metallogels via Supramolecular Coordination Complex Platforms: Metallogelation Induced Chirality Transfer

17-Jan-2018 | Yue Sun; Shuai Li; Zhixuan Zhou; Manik Lal Saha; Sougata Datta; Mingming Zhang; Xuzhou Yan; Demei Tian; Heng Wang; L ..., Journal of the American Chemical Society, 2018

Chiral self-assemblies constantly attract great interest because of their potential to provide insight into biological systems and materials science. Herein we report on the efficient preparation of alanine-based chiral metallacycles, rhomboids 1D and 1L and hexagons 2D and 2L using a Pt(II) ← ...

The State of the Art in Azaborine Chemistry: New Synthetic Methods and Applications

17-Jan-2018 | Zachary X. Giustra; Shih-Yuan Liu, Journal of the American Chemical Society, 2018

Boron–nitrogen heteroarenes hold great promise for practical application in many areas of chemistry. Enduring interest in realizing this potential has in turn driven perennial innovation with respect to these compounds’ synthesis. This Perspective discusses in detail the most recent advances in ...

Pushing up the Size Limit of Metal Chalcogenide Supertetrahedral Nanocluster

16-Jan-2018 | Xiaofan Xu; Wei Wang; Dongliang Liu; Dandan Hu; Tao Wu; Xianhui Bu; Pingyun Feng, Journal of the American Chemical Society, 2018

The cubic ZnS structure type and the size-dependent properties of related nanoparticles are of both fundamental and technological importance. Yet, it remains a challenge to synthesize large atom-precise clusters of this structure type. Currently, only supertetrahedral clusters with 4, 10, 20, and ...

Synthesis of Allylic Alcohols via Cu-Catalyzed Hydrocarbonylative Coupling of Alkynes with Alkyl Halides

16-Jan-2018 | Li-Jie Cheng; Shahidul M. Islam; Neal P. Mankad, Journal of the American Chemical Society, 2018

We have developed a modular procedure to synthesize allylic alcohols from tertiary, secondary, and primary alkyl halides and alkynes via a Cu-catalyzed hydrocarbonylative coupling and 1,2-reduction tandem sequence. The use of tertiary alkyl halides as electrophiles was found to enable the ...

Shape-Control of Pt–Ru Nanocrystals: Tuning Surface Structure for Enhanced Electrocatalytic Methanol Oxidation

16-Jan-2018 | Liang Huang; Xueping Zhang; Qingqing Wang; Yujie Han; Youxing Fang; Shaojun Dong, Journal of the American Chemical Society, 2018

Despite the fact that both electrochemical experiments and density functional theory calculations have testified to the superior electrocatalytic activity and CO-poisoning tolerance of platinum–ruthenium (PtRu) alloy nanoparticles toward the methanol oxidation reaction (MOR), the facet-dependent ...

Reticular Electronic Tuning of Porphyrin Active Sites in Covalent Organic Frameworks for Electrocatalytic Carbon Dioxide Reduction

16-Jan-2018 | Christian S. Diercks; Song Lin; Nikolay Kornienko; Eugene A. Kapustin; Eva M. Nichols; Chenhui Zhu; Yingbo Zhao; Chr ..., Journal of the American Chemical Society, 2018

The electronic character of porphyrin active sites for electrocatalytic reduction of CO2 to CO in a two-dimensional covalent organic framework (COF) was tuned by modification of the reticular structure. Efficient charge transport along the COF backbone promotes electronic connectivity between ...

Photocontrolled Reversible Guest Uptake, Storage, and Release by Azobenzene-Modified Microporous Multilayer Films of Pillar[5]arenes

16-Jan-2018 | Tomoki Ogoshi; Shu Takashima; Tada-aki Yamagishi, Journal of the American Chemical Society, 2018

Using the pillar-shaped architecture of pillar[5]arenes, we constructed microporous multilayer films with azobenzene groups on the top surface by layer-by-layer assembly of cationic and anionic pillar[5]arenes. Guest uptake, storage, and release by the microporous films were regulated through ...
