Metal–organic frameworks (MOFs) have shown great promise in catalysis, mainly due to their high content of active centers, large internal surface areas, tunable pore size, and versatile chemical functionalities. However, it is a challenge rationally design construct MOFs that can serve as highly stable reusable heterogeneous catalysts. Here two new robust 3D porous metal-cyclam-based zirconium MOFs, denoted VPI-100 (Cu) (Ni), been prepared by modulated synthetic strategy. The are assembled...
Ligand-to-metal charge transfer (LMCT) excited states showcase promise in enabling photochemical reactions. This article details design principles to enable low energy LMCT and notable examples that drive reactions from these states.
Plants from several families (Chenopodiaceae, Gramineae, Compositae) accumulate betaine (glycine betaine) in response to salt or water stress via the pathway: choline → betainal (betaine aldehyde) betaine. Betaine accumulation is probably a metabolic adaptation stress. Intact protoplasts leaves of spinach ( Spinacia oleracea ) oxidized [ 14 C]choline and betaine, as did protoplast lysates. Upon differential centrifugation, C]choline-oxidizing activity lysates sedimented with chloroplasts....
A survey was developed and implemented to determine how pervasively safety principles cultural expectations are included in the chemistry curriculum at undergraduate level. The completed by first-year doctoral candidates chemical/pharmaceutical sciences. majority of respondents were trained use Safety Data Sheets (SDSs) PubChem. Additionally, a (61%) reported frequent discussions prior performing experiments their laboratory courses. In contrast, similar occurred infrequently research...
Ipomoeassin F (Ipom-F) is a plant-derived macrocyclic resin glycoside that potently inhibits cancer cell growth through blockage of Sec61-mediated protein translocation at the endoplasmic reticulum. Recently, detailed structural information on how Ipom-F binds to Sec61α was obtained using Cryo-EM, which discovered polar interactions between asparagine-300 (N300) in and four oxygens are crucial. One from carbonyl group C-4 fatty acid chain. In contrast, our previous structure–activity...
Understanding the landscape of molecular photocatalysis is vital to enable efficient conversion feedstock molecules targeted products and inhibit off-cycle reactivity. In this study, light-promoted reactivity [RuCp*2]+ was explored via electronic structure, photophysical, photostability studies within a photocatalytic hydrogen evolution cycle assessed. TD-DFT calculations support assignment low-energy ligand-to-metal charge transfer transition (LMCT) centered at 500 nm, where an electron...

Metal-organic cages are a class of supramolecular structures that often require the careful selection organic linkers and metal nodes. Of this class, few examples metal-organic exist where nodes composed main group metals. Herein, we have prepared an aluminum-based cage, H8[Al8(pdc)8(OAc)8O4] (Al-pdc-AA), using inexpensive commercially available materials. The cage formation was achieved via solvothermal self-assembly solvated aluminum pyridine-dicarboxylic in presence capping agent, acetic...
