20090131656 | METHODS OF NANOASSEMBLY OF A FRACTAL POLYMER AND MATERIALS FORMED THEREBY - The invention relates to the formation of synthesized fractal constructs and the methods of chemical self-assembly for the preparation of a non-dendritic, nano-scale, fractal constructs or molecules. More particularly, the invention relates to fractal constructs formed by molecular self-assembly, to create synthetic, nanometer-scale fractal shapes. In an embodiment, a nanoscale Sierpinski hexagonal gasket is formed. This non-dendritic, perfectly self-similar fractal macromolecule is comprised of bisterpyridine building blocks that are bound together by coordination to 36 Ru and 6 Fe ions to form a nearly planar array of increasingly larger hexagons around a hollow center. | 05-21-2009 |
20090171088 | REVERSIBLE SELF-ASSEMBLY OF IMBEDDED METALLOMACROCYCLES WITHIN A MACROMOLECULAR SUPERSTRUCTURE - In accordance with the present invention, there is provided a method for preparing a reversible, self-assembly of an imbedded hexameric metallomacrocycle within a macromolecular superstructure. The method occurs by an intramolecular mechanism in which a macromolecular skeleton possesses multiple ligands capable of reversible assembly-disassembly triggered by the presence of metal ions. | 07-02-2009 |
20100001235 | CONSTRUCTION OF QUANTUM DOTS VIA A REGIOSELECTIVE DENDRITIC FUNTIONALIZED CELLULOSE TEMPLATE - The invention is directed to quantum dot nanoparticles and methods of preparation. Using regioselective dendritic functionalized cellulose, quantum dots may be embedded in the modified cellulosic material. The quantum dot nanoparticles provide use for biotechnology or biomedicinal applications. Photooptical properties and morphology for use in as well as its biocompatibility were investigated. | 01-07-2010 |
20100013382 | METHODS FOR PRODUCING MATERIALS WITH PHOTO AND ELECTROLUMINESCENCE PROPERTIES AND SYSTEMS USING SUCH MATERIALS. - The invention is directed to a method of preparing polymeric metallomacrocycles having measurable photo- and electroluminescence properties and devices using such materials. In an embodiment an O-hexyl-3,5-bis(terpyridine)phenol ligand has been synthesized and transformed into a hexagonal Zn(II)-metallomacrocycle by a facile self-assembly procedure capitalizing on terpyridine-Zn(II)-terpyridine connectivity. The material is usable in an OLED device based on the photo- and electro-luminescence characteristics thereof. | 01-21-2010 |
20100041859 | CONVENIENT SYNTHESIS OF 1 --> 3 C-BRANCHED DENDRONS - In accordance with the present invention, there is provided a method of preparing higher generation 1→3 C-branched polyamide dendrons. The combination of commercially available acryloyl chloride with 1→3 C-branched amines, e.g., di-tert-butyl 4-[2-(tert-butoxycarbonyl)ethyl]-4-aminoheptanedioate, resulted in generally high yields of acryl amides, which upon treatment with other reagents, generated the desired higher generation dendrons. These second and third generation dendrons were fully characterized and compared to the samples prepared from a convergent synthesis. | 02-18-2010 |
20100133471 | DENDRON-TETHERED AND TEMPLATED QUANTUM DOTS ON CARBON NANOTUBES - The present invention provides an example for the construction of stable quantum dots, such as CdS quantum dots, on the surface of carbon nanotubes (CNTs) templated and stabilized, such as by attached 1→3 C-branched amide-based dendrons. The construction and method of preparation is applicable to both single- and multi-walled carbon nanotubes, other types of appropriately modified polymeric and oligomeric materials, along with the use of many other types of dendrons, and other materials capable of forming quantum dots. | 06-03-2010 |
20100286395 | METAL-MEDIATED REVERSIBLE SELF-ASSEMBLY OF CARBON NANOTUBES - There is provided a method and nanocomposite for the reversible assembly of nanotubes, such as oxidized single wall carbon nanotubes, based on metal coordination. The method produces a thermally stable, neutral nanocomposite possessing enhanced mechanical, electrical, physical and chemical properties for example. Disassembly can be provided by treatment with a competing ligand compound. | 11-11-2010 |
