On-surface synthesis is the bottom-up construction of covalent bonds between molecular building blocks, which has been greatly developed during past decade. Dozens reactions have successfully realized and scrutinized on various surfaces with help surface science techniques combined theoretical calculations. Functional nanoarchitectures such as one-dimensional nanowires, nanoribbons two-dimensional nanonetworks constructed explored in several potential applications. In fact, generation...
Thermally stable Au single-atoms supported by monolayered CuO grown at Cu(110) have been successfully prepared. The charge transfer from the support to single atoms is confirmed play a key role in tuning activity for CO oxidation. Initially, negatively charged single-atom active oxidation with its adjacent lattice O atom depleted generate an vacancy monolayer. Afterward, neutralized, preventing further reaction. produced can be healed exposure O2 400 K and accordingly reaction restored.
1,4-diiodotetrafluorobenzene (1,4-DITFB) is an excellent halogen bonding donor and used to assemble organic phosphorescent co-crystal with carbazole in which 1,4-DITFB expected act as a functional synthon, the cement link molecules by heavy atom perturber enhance phosphorescence of emitter spin–orbital coupling.

Cubic inorganic perovskite CsPbI3 is a direct bandgap semiconductor, which promising for optoelectronic applications, such as solar cells, light emitting diodes, and lasers. The intrinsic defects in semiconductors play crucial roles determining carrier conductivity, the efficiency of recombination, so on. However, thermodynamic stability defect physics are still unclear cubic CsPbI3. By using first-principles calculations, we study process find out that window growth quite narrow...

Reductive cross-coupling provides facile access to organogermanes, but it remains largely unexplored. Herein we report a nickel-catalyzed reductive Csp3–Ge coupling of alkyl bromides with chlorogermanes. This work has established new method for producing alkylgermanes. The reaction proceeds under very mild conditions and tolerates various functionalities including ether, alcohol, alkene, nitrile, amine, ester, phosphonates, amides, ketone, aldehyde. application this the modification...
Allergic diseases are immune system dysfunctions mediated by mast cell (MC) activation stimulated specific allergens. However, current small molecular MC stabilizers for allergic disease prevention often require multiple doses over a long period of time and associated with serious side effects. Herein, we develop diselenide-bridged mesoporous silica nanostabilizer, proving that it could specifically target sensitized MCs via the recognition IgE aptamer IgE. Meantime, can also mitigate...

Mechanochemistry refers to chemical reactions induced by mechanical forces. Due different reaction mechanisms, products obtained through mechanochemistry can be distinct from those produced thermochemistry and photochemistry. Scanning probe microscopy is a powerful tool for studying single-molecule mechanochemical processes. Mechanical force vector that has both magnitude direction. Previous studies have focused on triggering forces measuring their magnitude. In this work, we use the...
Abstract Lanthanide double‐decker phthalocyanine (LnPc 2 ) complexes are highly coveted for their prospective uses in ultrahigh‐density data storage and quantum computing.
