The separation of isomeric C4 paraffins is an important task in the petrochemical industry, while current adsorbents undergo a trade-off relationship between selectivity and adsorption capacity. In this work, pore aperture cage-like Zn-bzc (bzc=pyrazole-4-carboxylic acid) tuned by stepwise installation methyl groups on its narrow to achieve both molecular-sieving high n-C4 H10 uptake. Notably, resulting Zn-bzc-2CH3 (bzc-2CH3 =3,5-dimethylpyrazole-4-carboxylic can sensitively capture exclude...
Iron was used as the catalyst for direct C-H functionalization/C-S bond formation under mild conditions. Various substrates could afford benzothiazoles in moderate to excellent yields. Preliminary mechanistic studies revealed that pyridine played a crucial role high yields and selectivities.
Abstract Due to the fascinating structures and wide applications, porous materials with open frameworks have attracted more attentions. Herein, a novel two‐dimensional (2D) halogen‐bonded organic framework ( XOF–TPPE ) was successfully designed fabricated by iodonium‐bridged N⋅⋅⋅I + ⋅⋅⋅N interactions between pyridyl groups I for first time. The formation of its linear analogue monitored 1 H NMR, UV–Vis, X‐ray photoelectron spectroscopy (XPS), IR, SEM, TEM, HRTEM selected‐area electron...
A novel macrocycle of B/N-doped calix[4]arene (C-BN) was synthesized by a one-shot double boronation. Owing to the structural tension and electron-donating properties nitrogen atoms in macrocycle, reaction selectively proceeds between adjacent benzene rings outside macrocycle. C-BN shows highly centrosymmetric structure with two multiple resonance (MR) fragments bridged tertiary amine groups at 1,3 positions ring. Benefiting from large intermolecular distance (>4.6 Å) MR-emitting cores, also...
The development of diverse linking methods in organic framework materials is crucial for advancing science and engineering. [N-X+-N] halogen bonds are a powerful tool constructing supramolecular aggregates, including halogen-bonded frameworks (XOFs), which have emerged as new class frameworks. However, the existing production XOFs often yields insoluble AgI byproducts, impeding XOF crystallinity, performance, functionality. Hence, alternative preparation required. Here, we present novel...
