Summary: Novel amorphous iridium(III)-acetanilide porous coordinated polymer (PCPs) was successfully synthesized in 11 min by applying high energy laser-assisted one-pot synthesis technique. The structural and micro-structural features of initially produced square planar units of amorphous Ir-acetanilide-complex as well as Ir-PCPs were carefully characterized. Additionally, Ir-PCPs exhibited a relatively high BET surface area of -1678 m2 g-1, making it a strong potential candidate for CO2 capture. Moreover, the antiproliferative activities of the novel synthesized cyclometalated Ir-PCPs were tested and showed promising results.

Summary: Due to increased CO2 emissions, efforts have been made in developing CO2 capture methods. In this study, an electrodeposition approach was used to grow HKUST1 MOFs into graphene oxide (GO) nanochannels, resulting in a high CO2 adsorption capacity and selectivity due to the synergistic effect of HKUST-1 and GO. The composite membrane also exhibited improved mechanical properties compared to pristine GO membrane. This method shows promise for developing high-performance CO2 capture membrane systems under normal temperature and pressure conditions, and can be applied to other MOFs@GO composite membranes.

Summary: Integrating metal-organic frameworks onto textile fibers enables the preparation of solid catalysts for practical protective applications such as the degradation of chemical warfare agents. Multiple variables that affect the catalytic activity and permeability of an MOF-polymer fiber composite have been systematically studied. Activation methods, MOF mass loadings, and MOF particle size are the most crucial parameters that affect the resulting composite.

Summary: This study presents a metal-organic framework (MOF)-derived hybrid solid acid catalyst with improved acidity for promoting amine regeneration. The TiO2 coating effectively prevents active components stripping from the catalyst surface, increasing CO2 desorption rate and reducing energy consumption. Proposed N-C bond rupture and proton transfer mechanisms contribute to the advancement of CO2 capture technology with lower energy duty.

Summary: A novel Zr-IV-based perfluorinated metal-organic framework (PF-MOF) was synthesized under solvent-free conditions, and it was found that Zr-IV can replace Zr fumarate to change the framework structure. Furthermore, introducing perfluorinated linkers through postsynthetic exchange reactions can enhance the CO2 adsorption capacity, and solid-state density functional theory calculations provided insights into the thermodynamics of CO2 adsorption.
