与不同的学生、同事和学者的交流沟通对产生高质量的科学成果至关重要。要解决我们面临的全球性问题，不能孤立于一个实验室、一个机构甚至一个国家，而要在人类丰富的互动交流中实现。近年疫情大流行，线下会议变得更加困难，在同行评议的期刊上发表文章已成为科学传播的重要途径之一。作为一个学术团体和出版机构，中国化学会感谢广大学者的信任，可以选择CCS Chemistry发表您们的优秀成果并将其推广给全世界，我们为在传播化学科学及相关优秀成果方面所发挥的作用感到荣幸。

本期 CCS Chemistry（第 3 卷第 9 期），共有 22 篇文章，包括 7 篇通讯和 15 篇研究文章，包含了全合成、催化、仿生纳米传感器、分子磁电材料和有机太阳能电池等方向的杰出研究。这些文章不仅反映了化学的最新进展，还展示了其与生命和材料科学的紧密联系，下面是每篇文章的简短导读：

-Total Synthesis of Opioids. Do we have to grow fields of poppies to produce opioids for medicinal use? Yong Qin(秦勇), Wu Zhong (钟武) and coworkers report a scalable total synthesis of oxycodone, codeine, and several other opioids by harnessing a highly efficient bio-inspired Pd-catalyzed arene coupling process, demonstrating a potential application in the industrial manufacture of opioids.

-Total Synthesis of Rippertenol. Zhen Yang(杨震), Jian-Xian Gong(龚建贤), Jun-Kai Fu(傅俊凯) and coworkers report a concise synthesis of 4-desmethyl-rippertenol and 7-epi-rippertenol bearing a [6,6,5,7]-fused tetracyclic framework, the most impressive outcome for which is the application of the novel intramolecular photo-induced cyclization of α-cyclopropyl-substituted dienone to form the seven-membered ring in a diastereoselective manner.

-Photoluminescence Ln 3+ -Doped Nanoparticles. Maochun Hong(洪茂椿), Yongsheng Liu(刘永升) and coworkers develop a novel strategy to activate surface dark emitters in Eu3+-doped ultrasmall nanoparticles based on nanoparticle-size-dependent energy transfer from the loaded sensitizer of 2-naphthoyltrifluoroacetone to Eu3+ ions. These nanoparticles display no evident toxicity, making them potentially suitable for in vivo applications.

-Dicarbofunctionalization of Alkenes. Yi-Xia Jia(贾义霞) and coworkers develop stereoselective 1,2-diarylation and 1,2-arylalkynylation of trisubstituted alkenes via Pd-catalyzed Heck/Suzuki or Heck/Sonogashira domino sequences. A number of 3,3′-spirooxindoles bearing vicinal quaternary and tertiary stereocenters can be constructed in one step with excellent enantioselectivities and diastereoselectivities.

-Multicolor Luminescent Materials. Wei Huang(黄维), Qiang Zhao (赵强)and coworkers design and synthesize a compound consisting of carbazole and terpyridine group, and present a switchable multicolor system achieved by the delicate manipulation of sol–gel transformation and dynamic metal–ligand coordination. Furthermore, they demonstrate reversible multicolor information encoding and decoding based on this luminescent material.

-Catalytic Hydroamination of Alkenes. Shaolin Zhu(朱少林), You Wang(王优) and coworkers develop a nickel-hydride-catalyzed migratory hydroamination process for the selective installation of an amino group at either a benzylic position or a terminal position of various types of alkenes. Moreover, the practical value of this catalytic system is highlighted by the regioconvergent conversion of a mixture of isomeric olefins (petroleum-derived feedstock) to a value-added amine.

-Tertiary Alkylboronic Esters. Alkylboronic esters are classical synthetic intermediates, but general methods to access tertiary alkylboronic esters remain limited. Zhang Feng(冯璋) and coworkers report an iron-catalyzed borylation of unactivated alkyl chlorides, which delivers tertiary, secondary and primary alkylboronic esters with high efficiency, and allows the efficient late-stage borylation of biorelevant compounds.

-Chiral Plasmonic Nanomaterials. Minghua Liu(刘鸣华), Li Zhang(张莉) and coworkers synthesize novel helically grooved gold nanoarrows with tunable chiroptical properties, which can further self-assemble into a superhelix. They find an interesting chirality transfer from chiral plasmons to achiral molecules owing to the hotspots in the superhelix, which may help clarify the origin of chirality and chirality transfer in plasmonic nanomaterials.

-Intracellular K + Detection. Hong-Yuan Chen(陈洪渊), Wei-Wei Zhao(赵伟伟) and coworkers report a biomimetic nanosensor for intracellular K+ detection. The electrochemical signal is based on the change of ionic current delivered through a nanopipette that is coated with K+-responsive G-quadruplex DNA. This nanosensor has been demonstrated to be an accessible tool for monitoring the K+ concentration in a single cell after drug treatment.

-Photosensitization Switching. Peng Wu(吴鹏), Feng Li (李峰) and coworkers disclose a new function of double-stranded DNA (dsDNA) as a matrix in binding a photosensitizier, SYBR Green I, allowing activation of the triplet state by suppressing nonradiative transitions. Additionally, coupling the dsDNA-switched photosensitization with loop-mediated isothermal amplification can be used for colorimetric detection of hepatitis B virus.

-Catalyst for Tandem Reactions. Rong Cao (曹荣), Yuan-Biao Huang(黄远标) and coworkers fabricate a multifunctional catalyst of ultrafine Au nanoparticles stabilized by imidazolium-functionalized covalent triazine frameworks. This catalytic system exhibits excellent catalytic activity in a tandem deacetalization–condensation–reduction reaction, promoted by Lewis acid sites, Lewis base sites and the Au nanoparticles.

-DNA Nanomechanical Device. Xing-Hua Xia(夏兴华) and coworkers design a unique DNA nanomechanical device and investigate the interactive role of three important neuronal surface receptors. Interestingly, the DNA nanomechanical device has been used to modulate the growth and development of neurons in vivo, illustrating a potential application of DNA nanotechnology in the research on brain development.

-Molecular Ferroelectric. Zi-Shuo Yao(姚子硕) and coworkers present a new molecular ferroelectric, [CoII(en)3]SO4, which shows unprecedented two-step magnetic switching accompanied by paraelectric-ferroelectric-paraelectric phase transitions. They elucidate the structural correlation between magnetic and ferroelectric properties, which may promote the development of superior molecular magnetoelectric materials.

-Detection of Antibiotic-Resistant Bacteria. Pseudomonas aeruginosa is on the list of antibiotic-resistant “priority pathogens” published by World Health Organization. Xiaoguang Lei(雷晓光), Hai-Yu Hu(胡海宇) and coworkers synthesize a series of pseudopaline-conjugated fluorescent probes, and show their ability to selectively detect Pseudomonas aeruginosa in vitro or in vivo due to pseudopaline-mediated Zn2+ transport system.

-Direct Conversion of Methane. The photocatalytic direct conversion of methane to value-added chemicals is an attractive idea, but it is a great challenge to actually achieve. Yan Zhu(祝艳), Mingyang Chen(陈名扬) and coworkers disclose that a double-crown-like nickel-thiolate cluster is capable of converting methane with O2 to methanol and formic acid under visible light irradiation, with no CO2 byproduct produced.

-Potassium-Ion Batteries. To address the sluggish kinetics of K+ in potassium-ion batteries, Yongbing Tang(唐永炳) and coworkers develop a highly effective strategy of hybridizing the electrolyte with a small amount of Li+ ions, which may function as “ionic drills” to open diffusion channels for K+ ions in the host electrode. The optimized K+-based full battery displays excellent rate performance with a specific capacity of 106 mAh/g at a current rate of 5 C.

-Molecular Magnetism. You Song(宋友), Johan van Tol, Xing-Long Wu(吴兴龙), Zhenxing Wang(王振兴) and coworkers study the magnetic relaxation and quantum coherence of a low-spin mononuclear Co(II) complex and its deuterated analog at low temperatures. They discuss the underlying mechanism of deuterium isotope effects on spin dynamics, and present the direct evidence of spin–intramolecular vibration coupling.

-Li +– Ni Metal Batteries. Yi Zeng(曾毅), Fei Du (杜菲)and coworkers propose a hybrid aqueous battery by using Ni metal as the anode and LiMn2O4 as the cathode. The hybrid battery exhibits remarkable electrochemical performance, including an operating voltage of 1.1 V, a superior rate capability and long lifespan, providing a new battery design for improving energy storage performance with a safe and stable metal anode.

-Alzheimer’s Disease Therapy. Dong-Sheng Guo(郭东升), Tao Zhang(张涛) and coworkers fabricate a coassembly of two macrocyclic amphiphiles, guanidinium-calixarene (GCA) and cyclodextrin (CD). The GCA-CD coassembly exhibits a strong binding to β-amyloid (Aβ) due to multivalent recognition. As a result, it can disintegrate Aβ fibrils, mitigate the cytotoxicity induced by Aβ fibrils, and improve the cognitive deficits in Alzheimer’s disease mice.

-Organic Light-Emitting Diode. Although high-efficiency blue OLEDs have been realized in thermally activated delayed fluorescence materials, they need to be dispersed into host materials. Shanfeng Xue(薛善锋) and coworkers design a donor–π–acceptor-type molecule, namely tBuPCAPICN, as a “hot-exciton” fluorescent material. The non-doped tBuPCAPICN-based OLED device displays a pure-blue emission with an external quantum efficiency of 12.7%.

-Switchable Molecular Magnetic Compounds. There is increasing interest in the study of molecular compounds with tunable magnetic properties. Yuan-Zhu Zhang(张元竹) and coworkers synthesize hexanuclear {Fe2Co2M2} complexes by postmodification of the well-known {Fe2Co2} square unit. The desolvated {Fe2Co2Zn2} complex displays a reversible, thermally induced electron-transfer behavior with a transition temperature of 312 K.

-Nonfullerene Organic Solar Cells. Feng He(何凤) and coworkers synthesize two non-fullerene isomeric acceptors (BTIC-2Br-β and BTIC-2Br-γ) with different positions of bromine substituents. BTIC-2Br-γ-based solar cells with polymer PBDB-TF as the donor exhibit an outstanding power conversion efficiency of 16.5%, one of the highest values for brominated acceptors. In addition, the effects of bromine substitution position are investigated in depth.
