Chiral phosphoramidite ligand-modulated palladium auto-tandem catalysis for asymmetric dehydrogenative dienylation of imines with α-alkenes Sci. China Chem. (IF 10.4) Pub Date : 2025-01-14
Zhong-Sheng Nong, Hao-Fan Qian, Ying-Chun Chen, Pu-Sheng Wang, Liu-Zhu GongThe development of efficient processes allowing rapid access to complex chiral molecules from easily available alkenes is a long-term pursuit in the synthetic chemistry community. Transition metal-catalyzed asymmetric functionalization of allylic C–H bond represents a unique alternative toward this goal. However, enantioselective dehydrogenative transformation of olefins to value-added optically enriched

Ultrastrong room-temperature phosphorescence in cucurbit[8]uril-mediated crystalline supramolecules for ratiometric detection of phenethylamine Sci. China Chem. (IF 10.4) Pub Date : 2025-01-08
Qingyu Niu, Yingxiang Ye, Lingna Su, Xu He, Zhiqiang Li, Yu LiuIt is a great challenge to modulate purely organic fluorescence-phosphorescence dual emission in aqueous solution because the excited singlet and triplet states are in competition with each other. Herein, we report a crystalline 1:2 host-guest formed by self-assembly of 4-(4-bromophenyl)-pyridinium derivatives and cucurbit[8]uril, in which a rigid environment rich in weak interactions is directly demonstrated

Boosting aqueous nickel-zinc battery stability with bimetallic ion-integrated 1D metal-organic nanowires Sci. China Chem. (IF 10.4) Pub Date : 2025-01-08
Yihao Chen, Jin Liang, Yichun Su, Guoyin Zhu, Hengyue Xu, Hongye Ding, Guangxun Zhang, Dianheng Yu, Zizhou Shen, Yizhou Zhang, Wei Huang, Huan PangLimited by low conductivity, designing cathode materials with excellent electron transfer efficiency for high-performance nickel-zinc batteries (NZBs) remains challenging. In this study, a series of bimetallic metal-organic nanowires were fabricated by doping M ions in NiNTA, resulting in NiMNTA (M = Mg2+, Mn2+, Co2+, Zn2+, Ag+), and NixCo6−xNTA (x = 1, 2, 3, 4, 5). The proportions and types of metal

Haoyue Liang, Xingguo Zhong, Guxin Huang, Wenpan Liu, Yao Liu, Shuhao Wang, Deyu Wang, Hao Liu, Hao Wang, Tianyou Zhai, Huiqiao LiLi3VO4 has been a promising insertion anode material for Li-ion batteries, which has high theoretical capacity (up to ∼600 mAh g−1) and safe Li insertion voltage (0.5–1 V vs. Li/Li+). However, the low initial Coulombic efficiency (ICE) has always been the bottleneck limiting its commercialisation. Here, we propose a facile pre-lithiation method to controllably elevate the ICE by the post-treatment
