Porous nitrogen-doped hollow carbon spheres (NHCSs) with tailored particle size, nitrogen content and wall thickness were prepared by grafting a thin layer of poly(ionic liquid) as carbon precursor onto silica particle surface followed by carbonization and template removal. In the next step, Fe2O3 nanoparticles were a…
A series of two-dimensional diketopyrrolopyrrole-based low band gap conjugated polymers were synthesized. Replacing thiophene with thieno[3,2-b]thiophene in the side chain and bridge resulted in significant changes to the optical, electrochemical, and morphological properties of the polymers, as well as the subsequent…
Fluorol Red GK was developed as a on-off fluorescent probe of Au3+ based on Au3+ coordinating to cyano of probe, resulting in fluorescence quenching in a mixed aqueous environment, which was successfully applied to fluorescence imaging in living cells.
Three metal–organic frameworks (MOFs) with d10 metal ions, namely, {[Zn3(TDA)2(bpy)3]·(bpy)·10.5H2O}n (1), {[Zn3(TDA)2(azopy)2.5(H2O)]·4H2O}n (2) and {[Cd2K3(TDA)(HTDA)2(H2O)4]}n (3) (KH2TDA = potassium 1H-1,2,3-triazole-4,5-dicarboxylic acid, bpy = 4,4′-bipridine, azopy = 4,4′-azobispridine), have been successfully s…
Two porous nets have been prepared via a 2-step crystal engineering approach that links decorated trigonal prismatic [Cr3(μ3-O)(CO2)6] and [Cu3(μ3-Cl)(RNH2)6Cl6] molecular building blocks, MBBs. tp-PMBB-5-acs-1 is a rare example of a rigid acs underlying net whereas tp-PMBB-6-stp-1, an stp underlying net, exhibits fre…
New fluorescent benzimidazolium-based receptors selectively display the effective fluorescence quenching effect for biologically important anions, GTP and I(-), in aqueous solution of physiological pH 7.4. These affinities can be attributed to the strong ionic H-bonding along with additional interactions of fluorophor…
Well-designed graphene–TiO2–SnO2 ternary nanocomposites, in which the nanometer-sized TiO2 and SnO2 nanoparticles formed in situ uniformly anchored on the surface of reduced graphene oxide sheets, are synthesized by a solvothermal method combined with a hydrothermal two-step method. Although the contribution of anatas…
A novel gold atomic cluster-poly(3,4-ethylenedioxythiophene) (AuAC/PEDOT/Au) nanocomposite modified gold electrode has been designed for the trace level sensing of catechol. The addition of copper(II) enhanced the electro-catalytic oxidation of catechol via the formation of copper(I). The electrochemically synthesized…
A multi-responsive hydrophilic ABCBA-type pentablock copolymer, consisting of poly(ethylene glycol), poly(N-isopropylacrylamide), and poly(2-(diethylamino)ethyl methacrylate), PDEA-b-PNIPAM-b-PEG-b-PNIPAM-b-PDEA, was synthesized by consecutive reversible addition–fragmentation chain transfer (RAFT) polymerization. The…
MicroRNAs (miRNAs, miRs) are recognized as regulators of gene expression related to cellular development and diseases. In this study, we developed a carbon nanodot (C-dot)-based miR124a molecular beacon (miR124a CMB). The C-dots were purified from candle soot (cC-dots) by thermal oxidation. The double-stranded DNA oli…
Self-assembly of an achiral porphyrin at the interface between a chiral solvent and an atomically flat substrate renders the monolayer chiral, and a non-racemic solvent can even overrule the intrinsic expression of chirality in the self-assembly of chiral molecules.
OBJECTIVE: To prepare biocompatible ciprofloxacin-loaded carboxymethyl chitosan nanoparticles (CCC NPs) and evaluate their cell specificity as well as antibacterial activity against Escherichia coli in vitro. METHODS: CCC NPs were prepared by ionic cross-linking method and optimized by using Box-Behnken response surfa…
A novel strategy for the design and synthesis of functional materials with excellent acceptor properties is presented. The materials are based on homoleptic metal(II) complexes of azadipyrromethene (aza-DIPY) derivatives, and exhibit intense red absorption and high electron affinity. Their strong accepting properties…
The feasibility of renewable acetic acid as a direct fuel of SOFCs for sustainable electric power generation was investigated. To solve the problem of carbon deposition over conventional nickel cermet anodes, an advanced catalyst for acetic acid catalytic decomposition/internal reforming reaction was exploited. A comp…
Polystyrene nanoparticles stained with squaraine catenane endoperoxide exhibit remarkably high chemiluminescence and enable optical imaging of biodistribution in living mice. Whole-body chemiluminescence imaging was much more effective than fluorescence at identifying lung accumulation of the nanoparticles.
The anti-inflammatory and neuroprotective effects of trans-cinnamaldehyde (TCA) were investigated on the inflammatory cells and the dopaminergic degeneration in mice. TCA inhibited the up-regulation of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in the lipopolysaccharide (LPS)-induced inflammat…
We have isolated the stable as well as the metastable tautomers of 1-deazapurine in the solid state by exploiting principles of supramolecular selectivity in the context of cocrystal design.
A new class of green solvents, known as ionic liquids (ILs), has recently been the subject of intensive research on the extractive desulfurization of liquid fuels because of the limitation of traditional hydrodesulfurization method. In present work, eleven Lewis acid ionic liquids were synthesized and employed as prom…
The ring-opening polymerization of β-butyrolactone and lactide in solvent-free conditions and using NHC carboxylates as a (pre)catalyst is described. This class of catalysts enables the synthesis of aliphatic polyesters. These organocatalysts, which are easily synthesized, are remarkably robust, thus allowing the use…
The synthesis of a series of discrete lanthanide-capped polyoxovanadate cages is presented along with magnetic and electrochemical measurements which reveal a redox active dodecavanadate cluster with potential as a new functional building unit in polyoxovanadate chemistry.
