Crystal structure of pyridinium tetraisothiocyanatodipyridinechromium(III) pyridine monosolvate
In the crystal structure of the title compound, (C5H6N)[Cr(NCS)4(C5H5N)2]·C5H5N, the CrIII ions are octahedrally coordinated by four N-bonding thiocyanate anions and two pyridine ligands into discrete negatively charged complexes, with the CrIII ion, as ...

Click chemistry has evolved from making covalent connections to also breaking bonds. Here, a cascade assembly is reported that combines these maneuvers to build multifunctional biomolecular scaffolds in a modular one‐pot reaction. The unifying azide release‐tetrazine hub clicks with a trans‐cyclooctene tag, rapidly liberates N,N‐dimethylaniline to ...

Abstract DNA‐encoded libraries (DELs) enable large‐scale screening for hit identification, but accessing sp3‐rich, three‐dimensional chemotypes beyond flat, aromatic scaffolds remains challenging. Multicomponent reactions (MCRs) assemble such complexity from simple building blocks in a single step, and reaction‐engineering strategies have extended on ...

Porous Carbon Materials for Carbon Dioxide Capture
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
