Exploration of mixed polyanionic compound for potential high-voltage cathode materials in sodium-ion batteries CCS Chem. (IF 11.2) Pub Date : 2024-04-09 Tianyi Song, Nanzhong Wu, Xiao Zheng, Xinyuan Zhang, Shu Guo, Qi Yan, Wenjiao Yao, Yongbing Tang
Mixed polyanionic compounds are potential cathode materials for sodium-ion batteries. Herein, considering the advantages of the strong inductive effect of sulfate and the diverse, flexible coordination modes of oxalate, we systematically explored mixed sulfate-oxalate systems and obtained three sodium-contained polyanionic compounds. Interestingly, the novel three-dimensional Na2Co(C2O4)(SO4)·xH2O

Donor-Acceptor MOFs featuring Tunable Triplet States for Multi-Stimulus Responsive Room-Temperature Charge Transfer Phosphorescence CCS Chem. (IF 11.2) Pub Date : 2024-04-09 Lin Geng, Kai Wang, Rui Sun, Chang-Tai Li, Xiao-Ru Li, Meng Zhang, Mei-Hui Yu, Ze Chang, Xian-He Bu
Room-temperature phosphorescence (RTP) has drawn considerable attention due to its fascinating applications. Herein, we report the achievement of multi-stimulus responsive RTP by utilizing the customizable donor-acceptor (D-A) MOF platform for charge-transfer (CT) based triplet state tuning. A succession of electron-rich donors was introduced into the triazine-based electron-deficient framework ( NKU-Mg-2)

A golden touch in the design of multifunctional porphyrin metallacages: Host-guest chemistry for drug-target interactions. CCS Chem. (IF 11.2) Pub Date : 2024-04-03 Tamara Rodríguez-Prieto, Darren Wragg, Nicole Heiduk, Mihyun Park, Nicole Strittmatter, Roland A. Fischer, Angela Casini, Guillermo Moreno-Alcántar
The use of three-dimensional self-assembled metallacages (MCgs) as multimodal drug platforms holds great promise. However, the synthesis of MCgs with increased complexity and functionality is a great challenge, and knowledge of the interaction of MCgs with biological targets is still lacking. In this context, this work reports on the integration of a gold(III) porphyrin scaffold into a prismatic metallacage

Asymmetric Nucleophilic Additions Promoted by Quaternary Phosphonium Ion Pair Catalysts CCS Chem. (IF 11.2) Pub Date : 2024-04-04 Lingzhu Chen, Youlin Deng, Tingting Li, Deyu Hu, Xiaoyu Ren, Tianli Wang
Chiral quaternary phosphonium ion pair catalysis showcases a distinctive catalytic and stereoinductive mode arising from the synergy between ionic and noncovalent interactions. Over the recent decades, this methodology has been widely adopted to facilitate enantioselective nucleophilic addition reactions, including conjugate addition, Henry reaction, Mannich reaction, Strecker reaction, and hydrophosphonylation
