Promising Deep‐Ultraviolet Birefringent Materials via Rational Design and Assembly of Planar π‐Conjugated [B(OH)₃] and [B₃O₃(OH)₃] Functional Species

Jiahao Jiao, Meng Cheng, Rong Yang, Yuchen Yan, more

Angewandte Chemie International Edition > 61 > 27 > n/a - n/a

Birefringent materials play a significant role in modulating polarized light in optical communication and the laser industry. However, the discovery of deep ultraviolet (DUV, λ<200 nm) birefringent materials still faces a serious challenge. Herein, we propose hydroxylated π‐conjugated [B(OH)₃] and [B₃O₃(OH)₃] units for designing DUV birefringent materials. Innovatively, four new hydroxyborates...

Hydrophilic Catalysts with High Activity and Stability in the Aqueous Polymerization of Ethylene to High‐Molecular‐Weight‐Polyethylene

Fei Lin, Stefan Mecking

Angewandte Chemie > 134 > 27 > n/a - n/a

Water‐soluble synthetic transition metal catalysts have been studied extensively for many reactions, but for olefin polymerization such catalysts have been lacking. We report herein a straightforward synthesis of phosphinephenolato Ni^II catalysts endowed permanently with a hydrophilic sulfonate moiety bound to the chelating ligand. These catalysts’ hydrophilic active sites promote aqueous ethylene...

Hydrogen‐Bonded Supramolecular Polymer Adhesives: Straightforward Synthesis and Strong Substrate Interaction

Senbin Chen, Zeke Li, Yanggui Wu, Nasir Mahmood, more

Angewandte Chemie > 134 > 27 > n/a - n/a

High‐performance adhesives are of great interest in view of industrial demand. We herein identify a straightforward synthetic strategy towards universal hydrogen‐bonded (H‐bonded) polymeric adhesives, using a side‐chain barbiturate (Ba) and Hamilton wedge (HW) functionalized copolymer. Starting from a rubbery copolymer containing thiolactone derivatives, Ba and HW moieties are tethered as pendant...

Saving the Energy Loss in Lithium‐Mediated Nitrogen Fixation by Using a Highly Reactive Li₃N Intermediate for C−N Coupling Reactions

Gao‐Feng Chen, Aleksandr Savateev, Zihan Song, Haoyu Wu, more

Angewandte Chemie > 134 > 27 > n/a - n/a

Direct synthesis of N‐containing organic compounds from dinitrogen (N₂) can make synthetic chemistry more sustainable. Previous bottlenecks in lithium‐mediated N₂ fixation were resolved by loading Li‐metal anodes covered with the typical Li⁺ ion‐conducting solid electrolyte interface, which are subsequently allowed to react with N₂. The developed strategy allowed us to reach high Faradaic efficiencies...

Beyond Bioisosteres: Divergent Synthesis of Azabicyclohexanes and Cyclobutenyl Amines from Bicyclobutanes**

Kushal Dhake, Kyla J. Woelk, Joseph Becica, Andy Un, more

Angewandte Chemie > 134 > 27 > n/a - n/a

The development of two divergent and complementary Lewis acid catalyzed additions of bicyclobutanes to imines is described. Microscale high‐throughput experimentation was integral to the discovery and optimization of both reactions. N‐arylimines undergo formal (3+2) cycloaddition with bicyclobutanes to yield azabicyclo[2.1.1]hexanes in a single step; in contrast, N‐alkylimines undergo an addition/elimination...

Amine‐Catalyzed Copper‐Mediated C−H Sulfonylation of Benzaldehydes via a Transient Imine Directing Group**

Joe I. Higham, James A. Bull

Angewandte Chemie > 134 > 27 > n/a - n/a

Transient directing groups (TDGs) can provide a powerful means for C−H functionalization without requiring additional steps for directing group introduction and removal. We report the first use of a TDG in combination with copper to effect C−H functionalization. The regioselective copper mediated β−C(sp²)−H sulfonylation of aldehydes with sulfinate salts is accomplished using catalytic β‐alanine to...

A Ruthenium(II) Polypyridyl Complex Disrupts Actin Cytoskeleton Assembly and Blocks Cytokinesis

Martin R. Gill, Paul J. Jarman, Vanessa Hearnden, Simon D Fairbanks, more

Angewandte Chemie > 134 > 27 > n/a - n/a

The dinuclear Ru^II complex [(Ru(phen)₂)₂(tpphz)]⁴⁺ (phen=1,10‐phenanthroline, tpphz=tetrapyridophenazine) “RuRuPhen” blocks the transformation of G‐actin monomers to F‐actin filaments with no disassembly of pre‐formed F‐actin. Molecular docking studies indicate multiple RuRuPhen molecules bind to the surface of G‐actin but not the binding pockets of established actin polymerisation inhibitors. In...

Jiayun ZHOU, Yingdong LIU, Li XU, Zhimin ZHU, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 875 - 890

Luku alkali syenite is distributed throughout the southern end of the Hongge basic‐ultrabasic intrusion in Panzhihua, Sichuan, SW China. Using LA‐ICP‐MS, the alkali syenite intrusion yielded a zircon U‐Pb age of 264.5 ± 1.6 Ma, concordant with the ages of the E'meishan large igneous province (260 Ma). The intrusion displayed silica‐saturated, Al‐adequate and alkali‐rich signatures, with SiO₂ 62.07%–64...

Xiaosan ZHU, Minjie LU, Hongwei ZHENG

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 806 - 824

Calculated Bouguer gravity anomalies from the Andean orogenic belt interpreted as derived from regional gravity data to aid understanding of the lithospheric structure and tectonic evolution of the belt. These anomalies reveal lithospheric structures distributed throughout the belt, including linear and circular structures. NE‐trending structures reflect sinistral transpression across the northern...

Late Quaternary Slip Behavior of the Jinqianghe Fault in the Middle Qilian–Haiyuan Fault Zone, Northeastern Tibetan Plateau

Shumin LIANG, Wenjun ZHENG, Gan CHEN, Peizhen ZHANG, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 825 - 843

The Qilian–Haiyuan fault zone in the northeastern Tibetan Plateau has been the source of strong earthquakes in the region. In its middle segment, the Jinqianghe fault is an important active fault within the Tianzhu seismic gap; however, little is known about its slip behavior. To present a new horizontal displacement distribution along this fault, we used WorldView‐2 stereo pairs and unmanned aerial...

Xiaomin ZHU, Meizhou ZHANG, Shifa ZHU, Yanlei DONG, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 1024 - 1040

Researches into shale lithofacies, their sedimentary environments and relationship benefit understanding both of sedimentary cycle division and unconventional hydrocarbon exploration in lacustrine basins. Based on a 100∼300‐m‐thick dark shale, mudstone and limestone encountered in the lower third member of the Eocene Shahejie Formation (Es3l member) in Zhanhua Sag, Bohai Bay Basin, eastern China,...

Crustal Electrical Structure and Deep Metallogenic Potential in Northern Wuyi Area (South China), based on Magnetotelluric Data

Fan LUO, Qingtian LÜ, Kun ZHANG, Jiayong YAN, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 791 - 805

The northern Wuyi area, which is located in the northern Wuyi metallogenic belt, has superior mineralization conditions. The Pingxiang–Guangfeng–Jiangshan–Shaoxing fault (PSF) extends across the whole region regardless of whether or how the PSF relates to the near‐surface mineralization. We carried out an MT survey in the region and obtained a reliable 2D model of the crustal electrical structure...

Zixuan WANG, Yuanchuan ZHENG, Bo XU, Zengqian HOU, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 972 - 992

The Beiya porphyry‐skarn Au deposit is one of the largest gold deposits in China, temporally and spatially associated with Eocene intrusions in a post‐collisional setting in western Yunnan, China. In this study, we report new whole‐rock geochemistry, Sr‐Nd isotope, zircon U‐Pb geochronology and in situ zircon Hf‐O isotopes of quartz‐monzonite and biotite‐monzonite porphyries from the Beiya deposit...

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 1010 - 1023

Oil group separation, gas chromatography–mass spectrometry analysis of saturated hydrocarbons, carbon isotope analysis of fractions and tests on trace elements were all carried out to determine the origin of shallow Jurassic heavy oils in the northwestern margin of the Junggar Basin, northwestern China. Results showed that all the crude oils had been subjected to different degrees of biodegradation,...

Reservoir Characteristics of Fine‐grained Sedimentary Rocks in Saline Lakes in the Cenozoic Upper Ganchaigou Formation, Southwestern Qaidam Basin, NW China

Jun SHENG, Jincheng LIU, Yunlong LI, Haiyan ZOU, more

Acta Geologica Sinica ‐ English Edition > 96 > 3 > 1070 - 1081

Cenozoic fine‐grained sedimentary rocks in the southwestern Qaidam Basin, as typical salinized lacustrine sediments, are significantly different from those in other freshwater lakes under the impact of the high salinity in the lake. Many fine‐grained sedimentary rock samples were selected from the lower member of Neogene (N₁) in the Gaskule Oilfield, Qaidam Basin, northwest China, with the aim to...
