The understanding of cellular communication pathways in molecular detail is an important goal of bioorganic research. The synthesis of analogues of active substances (e.g. 1) to study the regulation of muscle contraction or the specific lipid modification of representative peptides (→2) to investigate their subcellular, targeted transfer to intracellular membranes are examples of the capability of organic synthesis is in the research of biological signal transduction mechanisms.

A twofold interpenetrated three-dimensional barium(II) metal-organic framework constructed from 2,2'-[terephthaloylbis(azanediyl)]diacetate: synthesis, structure, dihydrogen bonding and spectroscopic properties.

A new twofold interpenetrated 3D metal-organic framework (MOF), namely, poly[[μ-aqua-diaqua{μ-2,2'-[terephthaloylbis(azanediyl)]diacetato}barium(II)] dihydrate], {[Ba(CHNO)(HO)]·2HO}, (I), has been assembled through a combination of the reaction of 2,2'-[terephthaloylbis(azanediyl)]diacetic acid (TPBA, HL) with barium hydroxide and crystallization at low temperature. In the crystal structure of (I), the nine-coordinated Ba ions are bridged by two μ-aqua ligands and two carboxylate μ-O atoms to form a 1D loop-like Ba-O chain, which, together with the other two coordinated water molecules and μ-carboxylate groups, produces a rod-like secondary building unit (SBU). The resultant 1D polynuclear SBUs are further extended into a 3D MOF via the terephthalamide moiety of the ligand as a spacer.

We have developed a novel S-scheme mechanism to expand the photoresponse range of BiSiO. This study reports the successful creation of a CN/BS heterojunction photocatalyst, which is composed of g-CN and BiSiO. The synthesis was achieved through a simple two-step procedure, involving hydrothermal treatment and subsequent calcination.

Divergent synthesis of valuable molecules through common starting materials and metal catalysis represents a longstanding challenge and a significant research goal. We here describe chemodivergent, highly enantio- and regioselective nickel-catalyzed reductive and dehydrogenative coupling reactions of alkynes, aldehydes, and silanes. A single chiral Ni-based catalyst is leveraged to directly prepare three distinct enantioenriched products (silyl-protected trisubstituted chiral allylic alcohols, oxasilacyclopentenes, and silicon-stereogenic oxasilacyclopentenes) in a single chemical operation.

The accumulation of disposable face masks (DFMs) has become a significant threat to the environment due to extensive use during the COVID-19 pandemic. In this research, we investigated the degradation of DFMs after their disposal in landfills. We replicated the potential degradation process of DFMs, including exposure to sunlight before subjecting them to synthetic landfill leachate (LL).

Elemental analysis, infrared spectroscopy, and X-ray single crystal diffraction indicated that a novel metal-organic framework (Tb-MOF) designated as 0.5n[Hbpy]·[Tb(dpa)(HO)]·4nHO was synthesized successfully, (where Hdpa = 5-(3, 4-dicarboxy- phenoxy) isophenic acid, bpy = protonated 4,4'-bipyridine). Tb-MOF adopts a 3D network structure based on Tb ions and the (dpa) ligand through µ: η, η, η, η binding modes.
