Summary: Chitosan-pectin films containing Fe3O4 magnetic nanoparticles were prepared using solution casting method, creating biopolymer-based magnetically active materials. Physical interactions between the matrix and nanoparticles were confirmed by FTIR spectra and DSC results. The structure of the films was influenced by the interactions, leading to changes in mechanical properties. VSM and electrical analysis showed that the films exhibited ferrimagnetic behavior and increased dielectric constant with higher nanoparticle concentration. Additionally, the films demonstrated enhanced antimicrobial activity against both Gram-negative and Gram-positive bacteria. These findings highlight the potential of chitosan-pectin films with Fe3O4 magnetic nanoparticles in active and intelligent food packaging applications.

Summary: Traditionally, chemical modifications were used to modulate material active sites at ground states. However, this study demonstrates that molecular skeletons (MSs) and adjoint electron-configuration (MS-AEC) can be tuned at excited states (ESs) without chemical modifications. By using a porphyrinic metal-organic framework, the carbon capture performance is enhanced through the tuning of MS-AEC and electrostatic-potentials, which can be further modulated by metal cations. This work highlights the availability of static ESs and the potential of nonchemical modifications.

Summary: In this study, a nondeforming photo-responsiveness methodology was successfully developed by utilizing Cu-TCPP framework as a sorbent on graphite. The sorbent generated two types of adsorption sites that can modulate electron density distribution of the graphite layer in the c-axis direction, which can further evolve due to photo-stimulated excited states. The CO adsorption capability was improved from 0.50 mmol g(-1) at the ground state to 1.24 mmol g(-1) (0 degrees C, 1 bar) with visible light radiation instead of photothermal desorption.

Summary: Stimuli-responsive porous materials based on detachment mechanism were developed by fabricating a detachable porous organic polymer, DT-POP-1, from the polymerization of anthracene-containing monomer (AnMon) induced by 365 nm UV light. DT-POP-1 could detach into the monomer AnMon under 275 nm UV light or heat, and this polymerization/detachment process was reversible. The significant difference in porosity and adsorption capacity caused by the detachment makes the present detachable porous polymer highly promising in adsorptive separation and drug delivery.

Summary: Adsorption is a widely applied technique for producing high-purity chemicals. Traditional adsorbents have inflexible properties and suffer from selectivity-desorption trade-off. Photoresponsive adsorbents provide new avenues for adsorption techniques by regulating active sites through steric hindrance or tunable interactions. This concept summarizes recent efforts on the fabrication and application of photoresponsive adsorbents with tunable active sites, and presents future opportunities and challenges of photoregulation on adsorptive sites.

Summary: In this study, a new type of adsorbent with photo-responsive active sites for adsorptive desulfurization is reported. Coumarin monomers were incorporated into MIL-101(Cr) to construct the photo-responsive adsorbents. When triggered by UV light (>310 nm), coumarin monomers undergo dimerization and form a cyclobutane structure, resulting in increased uptake of 4,6-dimethyldibenzothiophene (4,6-DMDBT). Under irradiation of 254 nm UV light, coumarin dimers can transform back to monomers, leading to decreased adsorption of 4,6-DMDBT. The change in adsorption amount between PMOF and the coumarin monomers and dimers is up to 62.8%. This study may open up new avenues for the fabrication of adsorbents with on-demand active sites for various applications.
