Summary: Covalent triazine frameworks (CTFs) are promising porous organic compounds with stability, nontoxicity, nitrogen functionalities, and adjustable porosity. This study investigates the hydrogen storage capacities of different CTFs, and the results show that DCP has the highest capacity. DCP has high nitrogen content, high fraction of pyridinic N-sites, largest defect structure, highest crystallinity, and microporosity, contributing to its high hydrogen storage capability.

Summary: The study explores the application of photoswitches as light-responsive triggers for phase transitions of porous materials. By incorporating an azobenzene photoswitch in the backbone of a metal-organic framework, the researchers achieve light-induced structural contraction and gas adsorption control in the porous network. The complex mechanism of light-gated breathing is established, revealing a novel light-induced deformation mechanism of constrained azobenzene photoswitches.

Summary: This study proposed a pore matching strategy to synthesize sorbents with low energy penalty and superior capacity for efficient CO2 capture from flue gas. The tetraethylenepentamine-based PMAA@ZIF-8 samples obtained through this strategy exhibited low isosteric adsorption heat, high adsorption capacity, adsorption rate constant and selectivity compared to pristine ZIF-8. The CO2 physisorption mechanism onto tetraethylenepentamine-based PMAA@ZIF-8 was elucidated through various analysis techniques.

Summary: Step-shaped adsorption-desorption of gaseous payloads by flexible metal-organic frameworks can facilitate the delivery of large usable capacities with reduced energetic penalties. The multivariate linker approach is a powerful tool for tuning the phase change behavior of flexible frameworks. In this work, a multivariate framework was developed with a considerably reduced threshold pressure and desirable adsorption-desorption profile for efficient storage and delivery of weakly physisorbing species.

Summary: Metal organic frameworks (MOFs) and covalent organic frameworks (COFs) have emerged as strong alternatives for efficient hydrogen (H2) storage and purification. This review highlights the merging of molecular modeling and machine learning (ML) in the field of MOFs and COFs, focusing on H2 storage and purification. The use of computational screening and ML allows for the identification of optimal materials and extraction of hidden structure-performance relations for the design of novel MOFs.

Summary: Through the direct pyrolysis of MOFs assembled with Fe and Ni-doped ZnO nanoparticles, a novel Fe-1-Ni-1-N-C catalyst with neighboring Fe and Ni single-atom pairs on nitrogen-doped carbon support has been precisely constructed. The synergism of neighboring Fe and Ni single-atom pairs significantly boosts the electrocatalytic reduction of CO2, surpassing catalysts with separate Fe or Ni single atoms. The study reveals the importance of the communicative effect between adjacent single atoms for improved catalysis in single-atom catalysts containing multiple metal species.

Summary: This study presents a new methodology for the eco-synthesis of 2-amino-4H-chromenes using amino-grafted MOFs as catalysts under solvent-free and mild conditions. The catalytic performance is mainly influenced by the type and concentration of basic sites, while the porosity of the samples has minimal effect. This environmentally friendly alternative allows high yields in short reaction times with easily prepared catalysts.
