Covalent organic framework shows high isobutene adsorption selectivity from C₄ hydrocarbons: Mechanism of interpenetration isomerism and pedal motion

Wei Chen, Mian Li, Wen-Li Peng, Ling Huang, Chao Zhao, Acharya Dinesh, Wentao Liu, Anmin Zheng*

The gas adsorption/separation of covalent organic framework (COF) can be controlled by topology characteristics. A series of COFs with the diamond topology were screened for the selective adsorption of isobutene from other C₄ hydrocarbons via interpenetration, pedal motion and group substitution.

Selective adsorption of propene over propane on Li-decorated poly (triazine imide)

Yong Wang¹, Xiaoxia Jia¹, Libo Li*, Jiangfeng Yang, Jinping Li*

Coordinatively unsaturated metal sites (CUS) plays a dominating role in preferential adsorption of olefins over paraffins. Poly (triazine imide) (PTI) nanosheets can reach rapid gas adsorption equilibrium, due to its large surface-to-volume ratio. Combining the advantages of the CUS and the PTI nanosheets, we computationally demonstrate that the Li CUS–PTI complexes with slit pore architecture are potentially useful for C₃H₆/C₃H₈ adsorption separation.

Sung Ho Park, Sang Joon Lee*

Al³⁺-crosslinked poly(N-isopropylacrylamide) (PNIPAAm)/alginate composite selectively adsorbs Li⁺ ions with a low adsorption affinity, while rejecting cations with a high adsorption affinity due to a strong repulsive force by crosslinked Al³⁺. In addition, thermoresponsive PNIPAAm enables green recovery of Li⁺ ions via hydrophobic interaction.
