Summary: This article presents a strategy to actively engineer long-range charge transport in colloidal quantum dot assemblies by introducing ligand functionalities. The use of electronically coupled redox ligands enables a self-exchange chain reaction and facilitates long-range charge transport across the film. The different modes of charge transport in these assemblies and their manipulation through modulation of the Fermi level and redox ligand coverage are identified.

Summary: The study synthesized flower-like perylenetetracarboxylic-Zn(II) superstructures with Zn2+ ions and constructed a step-scheme heterojunction with Bi2WO6. This heterojunction significantly improved the photocatalytic efficiency for tetracycline degradation compared with pure Zn-PTC and Bi2WO6. The step-scheme charge transfer pathway effectively inhibited the recombination of photo-generated charges and utilized the different oxidation and reduction abilities of Zn-PTC and Bi2WO6.

Summary: This study presents the self-assembly and structure of a multi-metallic motif-based Cu-II metal-organic cage (MOC) functionalized with free bis(pyrazolyl)methane sites. PdII chloride can be quantitatively inserted into the MOC, resulting in a heterometallic cage structure. The choice of solvent in the metalation process determines the solid-state isomerism of the cage, providing a means to control the MOC's structural diversity and permanent porosity.

Summary: Three coordination compounds were synthesized and characterized from the reaction of copper(ii) bromide with the flexible bis-tetrazole organosulfur ligand, 1,2-bis(1-methyl-1H-tetrazole-5-ylthio)ethane (bmtte). Different reaction conditions led to the formation of polymeric 2 & INFIN;Cu2Br4(bmtte) (1), trinuclear [Cu3Br4(bmtte)(2)] (2), and tetranuclear [Cu2Br2(bmtte)](2) (3) compounds with different structures. The thermal stability, aqueous behavior, and reactivity of the compounds were investigated, and a new polymeric compound (8Cu4I4)-Cu-2(bmtte)(2) (4) was prepared through solid-state reaction and microwave irradiation. The redox behavior of the compounds was analyzed by cyclic voltammetry.

Summary: We reveal the anisotropic coupling of two distinct vibrational modes to the Cu(110) surface using the molecular nanoprobe technique. The N-H bending mode exhibits maxima perpendicular to the rows of the substrate, while the N-H stretching mode displays maxima along the rows.

Summary: We conducted a study on the excitation of individual vibrational modes with charge carriers moving on the Cu(110) surface. By using the molecular nanoprobe technique, we discovered the anisotropic coupling of two different vibrational modes to the substrate through the reversible switching of a molecule, specifically tautomerization of porphycene. Furthermore, we observed an inversion of the anisotropy between the N-H bending and stretching modes in porphycene adsorbed on Cu(110).

Summary: The authors developed a hollow mesoporous Mn/Zr-co-doped CeO2 tandem nanozyme (PHMZCO-AT) with regulated multi-enzymatic activities to disrupt the H2O2 homeostasis, achieve intensive NCDT, and induce tumor apoptosis and death. The nanozyme catalyzes the conversion of superoxide anion into H2O2 in the tumor region and inhibits the off-target decomposition of H2O2. The elevated H2O2 is then converted into toxic hydroxyl radicals, leading to tumor cell death.

Summary: In this study, we report three new metal-free photochemically active CO-releasing molecules (photoCORMs) based on a carbazole-fused 1,3-dioxol-2-one moiety. These photoCORMs can release CO and anticancer drugs upon one- and two-photon excitation, respectively. The results showed that the photoCORMs exhibited good cellular uptake and real-time monitoring ability of CO uncaging in cancerous cells. Interestingly, the dual photoCORM showed increased anticancer activity and accelerated the effectiveness of the anticancer drug, leading to significant improvement in tumor regression and overall survivability in a murine melanoma model.

Summary: Hydrogen sulfide (H2S) is an important gasotransmitter that plays a significant role in regulating various physiological activities. However, the current H2S delivery systems lack spatio-temporal control and can cause premature H2S release. In this study, a beta-carboline photocage-based H2S donor (BCS) was developed and formulated into two photo-controlled delivery systems: Pluronic-coated nanoparticles and a hydrogel platform. These systems showed stable behavior and precise control of H2S release through external light manipulation.

Summary: This work presents a molecular folding strategy to construct giant POSS molecules with inherent chirality. The folding of amino acid arms facilitated the chirality transfer from amino acids to ferrocene and POSS. The chiral orientation and chiroptical properties of POSS were found to depend on the substituents of alpha-amino acids. Through the kinetic nanoprecipitation protocol, chirality transfer from the molecular scale to the micrometer scale was achieved. This work opens up a new way to obtain discrete chiral molecular nanoparticles for potential chiroptical applications.
