According to molecular orbital theory forbenzenestructure, benzene ring involves the formation of three delocalised π– orbitals spanning all six carbon atoms, while the valence bond theory describes two stable resonance structures for the ring. ...
Atomically dispersed metal-N-C structures are efficient active sites for catalyzing benzene oxidation reaction (BOR). However, the roles of N and C atoms are still unclear. We report a polymerization-regulated pyrolysis strategy for synthesizing single-atom Fe-based catalysts, and present a systemati...
The synergistic properties of the combined admixture of benzenecarbonitrile and 5-bromovanillin (BNV) on the corrosion resistance of 1018 carbon steel in 1 M HCl was analysed with potentiodynamic polarization technique, weight loss method, micro-analytical studies and ATF-FTIR spectroscopy. Results ...
Metabolomics employs a range of mass spectrometry-based techniques, including liquid chromatography–mass spectrometry (LC-MS), gas chromatography–mass spectrometry (GC-MS), nuclear magnetic resonance (NMR), high-resolution mass spectrometry (HRMS), tandem mass spectrometry (MS/MS), and capillary ...
Versions Notes Abstract Anionic homo- and copolymerization of p-diethynylbenzene in the presence of n-BuLi in polar solvents was carried out. The use of hexamethylphosphortriamide (HMPA) makes it possible to synthesize a completely linear soluble polymer that does not have branching and phenylene ...
However, on the other hand, they were in favor of improving visible light absorption influence and promoting photoinduced charge separation and active oxygen species production (·O2−) using the surface plasmon resonance effect (SPR) [39,40,41,42]. The strong interaction of metal–support is ...
The typical guest probe tests showed that the substituted s3 cucurbit[n]uril(s) were not SQ[7], but rather SQ[6], because no included 1-adamantaneamine (ad) resonance signals were observed in the 1H-NMR spectrum of the s3-ad system [23], while the 1H-NMR spectra exhibited two sets ...
Rigid bay-conjugated perylene bisimide rotors: Solvent-induced excited-state symmetry breaking and resonance-enhanced two-photon absorption. J. Phys. Chem. B 2022, 126, 4939–4947. [Google Scholar] [CrossRef] [PubMed] Zhang, S.; Wu, D.; Jiang, X.; Xie, F.; Jia, X.; Song, X.; ...
The strong electron withdrawing inductive and resonance effects of this functional head tend to polarize the drug molecules to interact with nucleophilic sites of proteins resulting in the inhibition of activities of a wide range of enzymes [20,21]. The 5-substituted (X = Cl or -CH3) 2-...
Versions Notes Abstract The synthesis, and X-ray crystal structure of the inclusion host-guest complex of dodecamethylcucurbit[6]uril (DDMeQ[6]) with 1,4-dihydroxybenzene (DHOBEN) are reported. The complex crystallizes in the space group P21/c (No.14) with a =12.2847(4), b = 12.6895(...
