Summary: The researchers successfully engineered mesopores into microporous organic cages through host-guest interactions with long chain ionic surfactants, equipping the resulting hierarchically porous cage soft materials with charge-selective uptake and release abilities in solution. Interestingly, trapping enzymes within the cage turns it into a nanoreactor, leading to a 5-fold enhancement in enzymatic catalysis activity compared to free enzymes.

Summary: We successfully synthesized uniform covalent organic framework (COF) thin films using a solution-processable sphere transmutation process, which exhibited good crystallinity, porosity, and uniform thickness on a fluorine-doped tin oxide (FTO) surface. Four different COF thin films with different functional backbones were synthesized, and the TpEtBr COF film showed the lowest optical band gap and highest excited-state lifetime. All of the COF films exhibited significant photocurrent after illumination with visible light, indicating good photoactive characteristics. The out-of-plane photodetector device based on the TpEtBr COF thin film showed high photocurrent density and hole mobility, demonstrating the best photoactive properties.

Summary: Covalent organic nanotubes (CONTs) are porous one-dimensional frameworks connected through imine bonds via Schiff base condensation. The presence of two amine groups at the ortho position in the structurally demanding tetraaminotriptycene (TAT) building block leads to multiple reaction pathways between the ditopic aldehyde and the tetratopic amine. The synthesis and characterization of CONT-1 monomers, including the conversion of imine to imidazole bonding and the structural connectivity of CONTs, are investigated using various experimental techniques.

Summary: In this study, highly stable beta-keto-enamine-based COFs were reported as photo catalysts for metal-free C-B bond formation reactions. Three different COFs were used and their photocatalysis performances were monitored for 12 different substrates. The COFs showed moderate-to-high yields (up to 96%) depending on the substrate's molecular functionality. TpAzo COF exhibited the highest catalytic activity due to its high crystallinity, large surface area, low band gap, and suitable band position. The light absorbance capacity of the COFs played a crucial role during catalysis, as yields were maximized near the COF's absorption maxima. The synthesized COFs showed high photostability and could be reused for multiple (>5) catalytic cycles.

Summary: A cobalt-catalyzed, N,O-bidentate directing group-assisted C-H bond functionalization of benzamides with maleimides was developed for the facile access to isoindolone spirosuccinimides in good to excellent yields. This C-H bond activation and spirocyclization employing pyridine N-oxide as directing group provided very good substrate scope and tolerated various functional groups. Furthermore, the mechanistic investigation revealed that the C-H bond activation is the rate-determining step of this reaction.

Summary: The conversion of CO2 to a carbonaceous product using photocatalysis is an important solution for reducing CO2 emissions and dependence on nonrenewable resources. However, developing a metal-free catalyst that is selective and efficient in CO2 reduction is challenging. In this study, a molecular engineering approach was used to design a photoactive polymer with high CO2 permeability and low water diffusivity, promoting CO2 transfer and suppressing the HER reaction.

Summary: Twelve multicomponent solvate crystals were synthesized by slow evaporation method, consisting of 3,5-dinitrobenzoic acid and acetamide. These crystals were characterized by single-crystal X-ray diffraction, showing isostructural properties and continuous channels formed by weak intermolecular interactions. The solvate crystals exhibited amide-amide dimer homo synthons and R22 (8) motifs. The phase purity of solvate crystals was confirmed by powder X-ray diffraction, and their properties were further analyzed by nuclear magnetic resonance and differential scanning calorimetry. The importance of solvent properties, such as hydrogen bond donor/acceptor nature, size, and shape, in crystallization and crystal packing was discussed.
