Abstract Cobalt coordinated covalent organic frameworks have attracted increasing interest in the field of CO 2 photoreduction to CO, owing their high electron affinity and predesigned structures. However, achieving conversion efficiency is challenging since most Co related coordination environments facilitate fast recombination photogenerated electron-hole pairs. Here, we design two kinds Co-COF catalysts with oxygen atoms find that after tuning environment, reported framework catalyst Co-O...
Covalent organic frameworks (COFs) hold the potential in converting CO2 with water into value-added fuels and O2 to save deteriorating ecological environment. However, reaching high yield selectivity is a grand challenge under metal-, photosensitizer-, or sacrificial reagent-free conditions. Here, inspired by microstructures of natural leaves, we designed triazine-based COF membranes integration steady light-harvesting sites, efficient catalytic center, fast charge/mass transfer...
A class of artificial K+ channels formed by pillararene-cyclodextrin hybrid molecules have been designed and synthesized. These efficiently inserted into lipid bilayers displayed high selectivity for over Na+ in fluorescence electrophysiological experiments. The cation transport the is tunable varying length linkers between pillararene cyclodexrin. shortest channel showed specific transmembrane preference all alkali metal ions (selective sequence: > Cs+ Rb+ Li+ ), rarely observed channels....
It is very important to develop "smart" solvents that can integrate the advantages of homogeneous and heterogeneous reactions into one chemical process for enhanced reaction rate minimal environmental impact. In designing these solvents, applicability systems real processes strongly depends on phase behavior systems. this work, a novel class CO2-driven miscible–immiscible transition deep eutectic (DESs) has been explored. These DESs are composed alkanolamine compounds as hydrogen-bond...
The interactions of glycyl dipeptides (2-[(2-aminoacetyl)amino]acetic acid (commonly known as glycylglycine), 2-[(2-aminoacetyl)amino]-3-methylbutanoic glycyl-l-valine), and (2S)-2-[(2-aminoacetyl)amino]-4-methylpentanoic glycyl-l-leucine)) with sodium dodecyl sulfate (SDS) a function temperature in aqueous solution have been investigated by combination density, conductivity, fluorescence methods. standard partial molar volume (V2,ϕo), volumes transfer for dipeptide from water to SDS...

5-Hydroxymethylfurfural (HMF) is a key biobased platform compound for the production of high-value chemicals and fuels. However, separation purification HMF currently bottleneck production. In this work, novel class temperature-responsive deep eutectic solvent (DES)–water systems have been explored to selectively separate from reaction mixtures. The fructose dehydration was conducted in homogeneous DES–H2O systems, then, produced migrated DES-rich phase while unreacted retained H2O-rich upon...

The methanesulfenylation of various mercaptans and β-dicarbonyls has been investigated using in-situ generated methyl methanethiosulfonate (MMTS) from DMSO, facilitated by a catalytic amount (COCl)2. Employing the MMTS solution alongside Et3N led to synthesis range unsymmetrical disulfides with good yields. Furthermore, introduction [2H6]-DMSO enabled successful preparation [2H3]-disulfides. In case most β-dicarbonyls, was accomplished DBU, resulting in favorable
Abstract This paper considers robust output consensus of discrete‐time networked homogeneous negative imaginary (NI) systems under ℓ 2 external disturbances via integral quadratic constraints (IQCs). A necessary and sufficient condition for NI without poles at ±1 is obtained by the IQC‐based (D‐NI) stability result. Moreover, problem can be solved designing an unstable controller whose are related to transmission zeros D‐NI systems. The case with 1 also studied. These main results all...

Through first-principles calculations we study the electronic structures and optical properties of two-dimensional (2D) Sn[Formula: see text]Ti(Zr)[Formula: text]S 2 alloys. The results indicate that band gap value alloys is decreased continuously when Ti(Zr) concentration increased, which very beneficial to optoelectronic devices applications. Moreover, static dielectric constant increased in 2D In addition, also calculate imaginary part [Formula: text] dispersion along plane with different...
The binding selectivity of an adenine-monofunctionalized pillar[5]arene (H) with a series pyrimidine derivatives were investigated through 1H NMR experiments and density functional theory (DFT) study. High binding-selectivity was demonstrated. Typically, H displayed very strong strength 6-(2,4-dioxo-3, 4-dihydropyrimidin-1 (2H)-yl)hexanenitrile (G1) [Ka >105 M−1], up to about 3000-fold as compared 1-hexylpyrimidine-2,4(1H, 3H)-dione (G5) = 31 M−1]. ability G1 due the cooperative multiple...
