Photon correlation measurements of a number of single nanoparticles revealed that the probability of single-photon emission from the single nanoparticles clearly increases, compared with that of single chains embedded in host polymer matrices, poly(methyl methacrylate) (PMMA) and polystyrene (PS). The result suggested that even a single MEH-PPV chain with high molecular weight, which does not exhibit single-photon emission in PMMA and PS, is forced to exhibit single-photon emission by adopting \"compact\" chain conformation like nanoparticle. Efficient exciton migration and exciton annihilation processes in the compact chain conformation most probably result in the efficient single-photon emission from the single nanoparticle. The present results indicate that multi-quantum systems consisting of a large number of chromophores, such as the MEH-PPV, can be made to behave as single-photon sources by appropriately controlling their size.

Presently, the characterization of LCB in polymers is limited to the determination of the number of long chain branches per molecule. The ability to characterize other branching parameters such as the molecular weight of the branch and the shape of the branched molecule (star, comb, \"T\", \"H\", etc.)would have considerable value in material design. A new fractionation method, molecular topology fractionation (MTF), is described herein for the separation of polymer molecules based on LCB topology. This first successful practice of MTF uses monolithic columns to create a tortuous path having macropores or flow-through channels of the order of polymer molecular dimensions as the separation medium. Because long chain branched molecules are retained more than linear molecules of the same size, the method can be used to separate branched from linear chains. Performed in a thermodynamically good solvent, the key parameters influencing the onset of MTF include flow rate, macropore dimensions, and molecular weight of the polymer to be separated. The onset of the MTF mechanism is characterized by a flow rate-dependent reversal in the elution order of narrow molecular weight polystyrene standards, denoting a distinct change in retention mechanism. Below the reversal point, retention consistent with a hydrodynamic chromatography mechanism is active. Above the reversal point, a new mechanism yields increased retention with increasing molecular weight.", "tags": [], "relations": {}, "dateAdded": "2012-05-10T17:26:55Z", "dateModified":

The polymer was synthesised in fused silica capillaries (80 mm x 0.2 mm and 80 mm x 0.53 mm) and in borosilicate glass columns (90 mm x 1.0 mm and 90 mm x 3.0 mm) to yield different HPLC column designs. A comparison of those column dimensions regarding morphology as well as separation efficiency and applicability in bioanalysis is presented. The efficiency towards proteins as well as oligonucleotides was found to be considerably improved with decreasing column I.D. While a 5-protein mixture was baseline separated on all investigated column designs, the separation of small biomolecules like oligonucleotides or peptides on microbore and conventional size glass columns was strongly restricted in terms of resolution due to extensive peak broadening or the occurrence of peak asymmetry. Monolithic MS/BVPE capillary columns up to 0.53 mm I.D., however, proved to be applicable to the fractionation of the whole spectrum of biopolymers, including proteins, peptides, oligonucleotides as well as double-stranded DNA fragments. Due to the fact that reliable chromatography makes great demand on the robustness of the stationary phase, monolithic MS/BVPE capillaries were subjected to a comprehensive reproducibility study including run-to-run as well as batch-to-batch reproducibility.

To synthesize such nanorods, first \"dot-in-a-rod\" CdSe(dot)/CdS(rod) core/shell nanocrystals were prepared. Then a ZnS shell was grown epitaxially over these CdSe/CdS nanorods, which led to a fluorescence quantum yield of the final core-shell-shell nanorods that could be as high as 75%. The quantum efficiency was correlated with the aspect ratio of the nanorods and with the thickness of the ZnS shell around the starting CdSe/CdS rods, which varied from 1 to 4 monolayers (as supported by a combination of X-ray diffraction, elemental analysis with inductively coupled plasma atomic emission spectroscopy and high resolution transmission electron microscopy analysis). Pump-probe and time-resolved photoluminescence measurements confirmed the reduction of trapping at CdS surface due to the presence of the ZnS shell, which resulted in more efficient photoluminescence. These double shell nanorods have potential applications as fluorescent biological labels, as we found that they are brighter in cell imaging as compared to the starting CdSe/CdS nanorods and to the CdSe/ZnS quantum dots, therefore a lower amount of material is required to label the cells.

The structure has been established by spectral (UV-vis and H-1 NMR) data and confirmation in the latter case by a single-crystal X-ray diffraction study of [Cd(TaiMe)(12)center dot DMF] [where TaMe = 1-methyl-2-(ptolylazo)imidazole]. IJV-Light irradiation in a MeCN solution of Cd(RaaiR')(2)I-2 and [Cd(RaaiR')I-2-DMFI shows transto-cis isomerization of coordinated azoimiclazole. The reverse transformation, cis-to-trans, is very slow with visible light irradiation. Quantum yields (phi(t -> c)) of trans-to-cis isomerization are calculated, and the free ligand shows higher 0 values than their cadmium(II) iodo complexes. The cis-to-trans isomerization is a thermally induced process. The activation energy (E-a) of cis-to-trans isomerization is calculated by a control led-temperatu re experiment. The effects of the anions (Cl-, Br-, I-, and CIO4) and the number of coordinated azoimiclazoles (RaaiR') [Cd(RaaiR') or Cd(RaaiR')21 on the rate and quantum yields of photochromism are established in this work. A slow rate of photoisomerization of [Cd(RaaiR')(4)](CIO4)(2) compared to Cd(RaaiR')(12) or Cd(RaaiR')(2)X-2 may be associated with the increased mass and rotor volume of the complexes. The rate of isomerization is also dependent on the nature of X and follows the Sequence Cd(RaaiR')(2)CI2 < Cd(RaaiR')(2)Br-2 < Cd(RaaiR')(2)I-2. It may be related to the size and electronegativity of halide, which reduces the effective molar association in the order of I < Br < Cl and hence the rate.
