Multifunctional heteropentanuclear Al(3)Ln(2) (Ln = Nd, Eu, Yb) clusters with a novel structure exhibit significantly fluoride-enhanced lanthanide emission intensity and lifetime in both solid state and solution as well as unusual white-light emitting for an Al(3)Eu(2) complex.
Time-resolved extinction spectroscopy is employed to study the reaction kinetics in the shape-conversion reaction involving halide ions (including Cl(-), Br(-) and I(-)) etching (sculpturing) silver nanoplates. A series of time-resolved extinction spectra are obtained during the in situ etching process and the evoluti…
Silver nanoparticles (AgNPs) were successfully synthesized in situ on a paper matrix composed of ceramic fibers as the main framework and zinc oxide (ZnO) whiskers as a selective support for AgNPs. Paper-like ceramic fiber/ZnO whisker composites were prepared in advance using a high-speed, low-cost papermaking techniq…
Near-monodisperse polyaniline (PANI) colloids with controlled particle size (55–90 nm) were prepared by disperse polymerization of aniline in the presence of a steric stabilizer: polyvinylpyrrolidone (PVP). The silica-coated PANI colloidal nanospheres were further subjected to pyrolysis treatment at different temperat…
Towards a robust and universal functionalization procedure with alkanethiols for gold nanorods and plasmonic nanoparticles, a straightforward two-step approach is described.
Starting from a commercially available block copolymer, polystyrene-b-polybutadiene-b-polystyrene (SBS), micro-patterned polymer films were successfully prepared by evaporating SBS/carbon disulfide solutions with different concentrations under high humidity. The influence of solution concentration on the pore size and…
A novel class of efficient antenna complexes of Tb3+ based on the use of 3-phenyl-4-acyl-5-isoxazolone ligands has been designed, synthesized, characterized and their photophysical properties evaluated . The new heterocyclic β-diketonate complexes of Tb3+ exhibit high green luminescence efficiency in the solid state w…
A synthetic route to a magnesium-amidoborane complex and its role in the catalytic conversion of a substituted ammonia-borane RNH(2)BH(3) into HB(NHR)(2) is discussed.
A novel chiral open-framework structural hexanary chalcogenoborate, (K(3)I)[SmB(12)(GaS(4))(3)] (1), was obtained by a facile approach using boron as the reducing reagent; it shows weak SHG-activity and is transparent in the mid-IR region.
Surface-enhanced Raman scattering (SERS) spectroscopy can be used for the label-free determination and quantification of relevant small biometabolites that are hard to identify by conventional immunological methods, in the absence of labelling. In this work, detection is based on monitoring the vibrational changes occ…
Cryo-electron tomography of raspberry-like multicompartment micelles formed by a linear ABC triblock copolymer in water revealed that the fluorocarbon domains may be dispersed all over the hydrocarbon core.
Porous Cu/C composites and CuO nanostructures can be easily synthesized from coordination precursors between Cu(2+) and glycine, which are obtained simply by adding ethanol as a poor solvent into a Cu(2+) and glycine solution, and verified to be potential antibacterial agents and photocatalysts.
A mononuclear tri-spin single-molecule magnet based on the rare earth radical [Tb(hfac)3(NITPhOEt)2] (NITPhOEt = 4'-ethoxy-phenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been synthesized, structurally characterized and the alternating current signals show a slow relaxation of magnetization and frequency-dep…
Quadrupolar Bodipy dyes exhibiting TPA activity and high brightness with an emission at 660 nm were synthesized and internalized in HeLa cells, whereupon FLIM experiments were conducted.
Water-soluble pure hexagonal-phase NaYF(4):Yb(3+),Er(3+)/Tm(3+) nanoparticles were obtained by an ionothermal method for the first time which offers a new alternative in synthesizing such materials.
Unprecedented molecular and bidimensional compounds based on monovacant polyoxometalates capped by heterometallic 3d-4f {LnCu(3)(OH)(3)O} (Ln = La, Gd, Eu) cubane fragments have been characterized and their magnetic properties investigated.
Superparamagnetic nanoparticles (NPs) have been attractive for medical diagnostics and therapeutics due to their unique magnetic properties and their ability to interact with various biomolecules of interest. The solution phase based chemical synthesis provides a near precise control on NP size, and monodisperse magne…
The area of stimuli-responsive thin polymer films (brushes, layer-by-layer multilayered structures, networks, and hybrid systems with inorganic particles) is discussed in this article with the major focus on the properties and potential applications for sensors, smart coatings, miniaturized devices, and hierarchically…
A straightforward method for the rapid detection of the presence of glutathione S-transferase (GST)-tagged proteins from sample solutions using glutathione (GSH)-bound gold nanoclusters (Au@GSH NCs) with luminescence properties as the detection probes by simple observation with the naked eye was proposed in this study.
