Controllable photomechanical bending of metal-organic rotaxane crystals facilitated by regioselective confined-space photodimerization

Autor: Jun-shan Geng, Lei Mei, Yuan-yuan Liang, Li-yong Yuan, Ji-pan Yu, Kong-qiu Hu, Li-hua Yuan, Wen Feng, Zhi-fang Chai, Wei-qun Shi

Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-12 (2022)

The preparation of materials that display macro-mechanical responses to external stimuli is challenging. Here, the authors synthesize metal-organic rotaxane frameworks that contain photoactive axles as linkers; light irradiation triggers photodimeriz

Colossal negative thermal expansion in a cucurbit[8]uril-enabled uranyl-organic polythreading framework via thermally induced relaxation

Autor: Qiu-Yan Jin, Yuan-Yuan Liang, Zhi-Hui Zhang, Liao Meng, Jun-Shan Geng, Kong-Qiu Hu, Ji-Pan Yu, Zhi-Fang Chai, Lei Mei, Wei-Qun Shi

Publikováno v: Chemical Science.

A highly flexible uranyl-organic polythreading framework enabled by cucurbit[8]uril-based host–guest complexation exhibits remarkable negative thermal expansion behaviour through a relaxation-related mechanism.

Synthesis of Trapen Ligand-Based U(IV) and Th(IV) 2-Phosphaethynolate Complexes and Comparison of Covalency with Corresponding Ti(IV) Analogues

Autor: Kang Liu, Xiao-Wang Chi, Yan Guo, Qun-Yan Wu, Kong-Qiu Hu, Lei Mei, Zhi-Fang Chai, Ji-Pan Yu, Wei-Qun Shi

Publikováno v: Inorganic chemistry. 61(45)

The involvement of the 2-phosphaethynolate anion species with ambident nucleophilic properties serves as an essential protocol for synthesizing oxygen-bound or phosphorus-bound complexes. This work mainly describes the synthesis and characterization
