Summary: A spherical amine-functionalized mesoporous silica molecular sieve was synthesized using an acid hydrothermal method. This molecular sieve exhibited uniform and controllable pore sizes and a large number of amino groups. It was found to be highly efficient in selectively separating aromatic hydrocarbons containing two fused benzene rings from environmental water matrix. The high selectivity was attributed to size sieving and p-pi interactions between amine groups and aromatic hydrocarbons. A solid-phase extraction method coupled with high performance liquid chromatography detection was developed for the analysis of these aromatic hydrocarbons. The study provides inspiration and a reliable method for the separation, removal, and analysis of aromatic hydrocarbons.

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: 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 strategy was developed to improve the dispersity, switchability, and utilization of active sites in light-switchable metal-organic cages (LMOCs) by isolating them into the targeted pores of metal-organic frameworks (MOFs) using light-assisted precise size control. Furthermore, reversible trans/cis isomerization of light-switchable motifs in the LMOCs was achieved upon UV/vis-light irradiation, allowing for maximum control over CO2 adsorption behavior. This work provides a facile route for the development of new composite materials with isolated light-switchable motifs for tunable CO2 adsorption.

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.

Summary: This study presents a light-switchable metal-organic cage, NUT-102, incorporated with pendant azobenzene groups for controllable CO2 capture. By irradiating with visible light, the pores of NUT-102 can be exposed to favor CO2 adsorption, while irradiating with ultraviolet light can lead to the sheltering of the pores and reduction of CO2 adsorption. The controllable CO2 adsorption change can reach up to 65.2%.
