Three pillar[n]arenes (n = 8–10) were synthesized. X-ray analysis demonstrated that, different from early reported small 5, 6), these larger macrocycles gave rise to two cavities. 1H NMR and MS experiments revealed that pillar[9]arene complexed one n-octyltrimethyl ammonium in chloroform, while pillar[10]arene could complex two.
A pillar[5]arene decaamine has been synthesized and revealed to encapsulate linear diacids in neutral, alkaline, acidic conditions, driven by the hydrophobic electrostatic interactions, give rise pseudo[2]rotaxanes. Ion pair-bonded stoppers can further lock generate stable water soluble [2]rotaxanes.
α-Fetoprotein (AFP) is an important tumor biomarker. In particular, the overexpression of AFP-L3 associated with hepatocellular carcinoma (HCC). Accordingly, several hospitals have begun to employ ratio total AFP level (AFP-L3%) as new diagnostic evidence for HCC owing its high accuracy. However, current methods detection and are time-consuming, require multiple samples, lack in sensitivity specificity. Herein, we present a novel concept early diagnosis based on combination Raman frequency...
Abstract Ternary noble metal–semiconductor nanocomposites (NCs) with core–shell–satellite nanostructures have received widespread attention due to their outstanding performance in detecting pollutants through surface-enhanced Raman scattering (SERS) and photodegradation of organic pollutants. In this work, ternary Au@Cu 2 O–Ag NCs were designed prepared by a galvanic replacement method. The effect different amounts Ag nanocrystals adsorbed on the surfaces O SERS activity was investigated...
Reactions involving allenyl ion intermediates have been widely applied in the synthesis of functionalized allenes, but reactions radicals less studied and limited successful examples realized mainly by transition metal catalysis. We herein demonstrate generation N-heterocyclic carbene (NHC) organocatalysis their applications three-component radical relay 1,4-alkylcarbonylation 1,3-enynes without participation. This strategy could accommodate a collection different alkyl precursors such as...
We review the design of MOFs as heterogeneous photocatalysts, analysing research on their use in water pollutant degradation, splitting and CO 2 reduction. Advantages disadvantages MOFs-based catalytic mechanisms future are evaluated.
In this work, we cosputtered Ag and ZnSe on a polystyrene template to form three-dimensional (3D) Ag@ZnSe (x) structure. The 3D surface morphology material composition that provided abundant "hot spots" were controlled by adjusting the sputtering power of ZnSe, which was confirmed finite-difference time-domain (FDTD) simulation. introduction into noble metal also introduced charge-transfer (CT) effect system, CT path proven with two-dimensional correlation spectroscopy...
Tunable surface plasmon resonance (SPR) of silver (Ag) films fabricated via magnetron sputtering technology was achieved. The experimental findings demonstrated that the thickness Ag film gradually increased with increasing time, resulting in a red shift SPR peak. To investigate charge transfer (CT) induced by metal/probe molecule/organic semiconductor system, composite system composed nanoparticles, mercaptobenzoic acid (MBA), and polyaniline (PANI) prepared layered assembly method....

It shown that morphological goes through...
The first borate carbonate UV nonlinear optical material Pb7O(OH)3(CO3)3(BO3) was hydrothermally synthesized, which features a (3,9)-connected IrSi3-like structure constructed by Pb7O(OH)3(BO3) units and carbonates. This compound exhibits large second-harmonic generation (SHG) response about 4.5 times that of KH2PO4 (KDP), attributed to synergistic interactions between the stereoeffect Pb(II) cations coparallel BO3 CO3 triangles groups.
In this work, we report the enhanced catalytic reduction of 4-nitrophenol driven by Fe3O4-Au magnetic nanocomposite interface engineering. A facile solvothermal method is employed for Fe3O4 hollow microspheres and synthesis via a seed deposition process. Complementary structural, chemical composition valence state studies validate that as-obtained samples are formed in pure magnetite phase. series characterizations including conventional scanning/transmission electron microscopy (SEM/TEM),...
In this paper, we propose a novel and simple method for preparing dual-biomimetic functional array possessing both superhydrophobic peroxidase-like activity that can be used hydrogen peroxide (H2O2) sensing. The proposed is an integration innovation combines the above two properties surface-enhanced Raman scattering (SERS). We integrated series of well-ordered arrays Au points (d = 1 mm) onto copper (Cu)/silver (Ag) surface by replicating arrayed molybdenum template. Instead using...
In this study, we designed shell-dependent Ag@Cu<sub>2</sub>O core–shell nanoparticles (NPs) for SERS study. Compared to Cu<sub>2</sub>O NPs, NPs exhibited high activity because of the localized surface plasmon resonance (LSPR) from Ag core.
In this work, a molecularly imprinted polymer (MIP)-based SERS sensor for selective, sensitive, quantitative, and recyclable detection of paclobutrazol residues in complex environments has been proposed. strategy, Fe3O4@SiO2–Au@Ag (FSAA) nanocomposites with tunable Au@Ag interparticle gaps are constructed. Then, by tuning the nanogaps investigating enhancement mechanism FSAA, we achieve optimal substrate, FSAA-40. After combining MIPs, can selectively detect soil limit 0.075 μg/g. When...
