Definitions

  • the nanocrystal products of the present invention avoid the previously discussed problems.
  • the "as prepared" spherical nanoparticles are crystalline and are characterized by narrow relative size distributions (as low as ⁇ 10 %). More importantly, however, is the fact that they are functionalized with well-defined organic groups covalently bound to the particle surface. These organic functional groups may be altered both chemically and with respect to percent coverage on the surface. Such chemistry is tremendously useful in the following ways: 1) the organic functional groups, coupled with the size-dependent curvature of a particle surface, yield varying solubilities as a function of particle size.
  • the present invention provides techniques for the synthesis of various metallic nanocrystal materials in which the resultant particles are characterized by the following properties: (1) they are soluble and resoluble in various organic media, including organic solutions containing dissolved polymers; (2) they are stable as powders or monodisperse (non-aggregated) colloids under ambient conditions for at least several days; (3) they are stable for months when stored under low temperature conditions as powders or monodisperse (non-aggregated) colloids in solution; (4) they can exist as monodisperse entities (when prepared as organic colloids) which can be readily separated into arbitrarily narrow size distributions via various chemical and chromatographic techniques; (5) they can be prepared in at least gram quantities; (6) they may consist of a host of metallic elements prepared as either pure metal particles or alloys, synthesized from the combination of a host of specific metal-containing inorganic compounds, phase transfer catalysts, surface passivants, and reducing agents; (7) they are readily dispersed into various matrices or onto various substrates (gels,
  • a second example of a potential application of these materials deals with using silver particles in reprography.
  • reprographic processes which have stages that intimately depend on the nucleation and growth of small silver particles.
  • small silver particles form the amplification (latent image) center in conventional photographic processes.
  • This latent image center formed by the action of light on silver halide crystals, acquires catalytic properties that enable it to trigger the reduction of the entire silver halide crystal to metallic silver by the reducing agent of the developer.
  • uniform particle size distributions lead to uniform film quality, and small particle sizes lead to enhanced film resolution.
  • gold since gold is frequently used in small quantities as a sensitizer for photographic emulsions, the Au particles may be applicable here as well.
  • nanocrystals as functional units in innovative micro and nanoelectronic devices. These applications are based on the idea that two- and three-dimensional close-packed ordered arrays (superlattices) of these nanocrystals will exhibit novel electronic properties dominated by single electron phenomena, due to the quantum confined electronic properties of the individual particles as well as their collective coherence effects.
  • UV/vis UV-visible spectroscopy
  • IR infrared spectroscopy
  • Particle composition, size, and properties may be varied by means of the following changes: the variation of the metal precursor used, the variation of phase transfer reagents used or their omission from the synthetic procedure, the variation of one or more surface passivants used, the variation of the reducing agent used, or the variation of some of the reactant molar ratios, or any combination thereof.
  • the peak positions, line shapes, and peak-to-peak distance of the Au 4f doublet are the standard measure of the gold oxidation state.
  • the binding energies for the Au 4f doublet are 83.5(3) and 87.2(3) eV (peak-to-peak distance of 3.7 eV). These measurements are consistent with the Au oxidation state.
  • a separate solution consisting of 20 g of sodium dodecylsulfate (SDS) dissolved in 300 ml of deionized H 2 O was prepared. This yielded a 6.25 weight percent solution of SDS in H 2 O;
  • 1 ml of the 6 mg/ml Ag particle/hexane solution was added to 20 ml of the 6.25 weight percent solution of SDS in H 2 O resulting in a two-layer mixture (organic layer on top and aqueous layer on the bottom). This mixture was stirred vigorously for a period of 6 hours.
  • the film thickness was measured by profilometry to be 20 ⁇ m.
  • the dielectric measurements of the metal nanocrystal-doped polymer thin film yielded unique dielectric values as copared to the 'pure' or un-doped polymer.
  • the dielectric characteristics for the metal nanocrystal-doped polymer thin film were: a) dielectric constant - 15; b) breadown voltate - 1.2 kv/mm. As can be seen, the dielectric constant of the doped film increases by about a factor of 10.
  • dodecylamine-capped Pt nanocrystals were prepared and characterized according to the procedure of Example 7.
  • the particles used here for catalysis had an average domain size of approximately 25 A;

Abstract

La présente invention concerne la production de nanoparticules de métal organiquement fonctionnalisées. On procède pour cela en mélangeant un précurseur métallique avec un agent organique de passivation de surface, puis en faisant réagir le mélange résultant avec un réducteur de façon à générer un métal libre tout en liant l'agent de passivation à la surface du métal libre jusqu'à produire des particules de métal organiquement fonctionnalisées.
