  • Publication number: 20090171088
    Abstract: 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.

  • Publication number: 20090131656
    Abstract: 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.

  • Patent number: 7368512
    Abstract: A method of detecting unreacted termini within a dendritic structure is achieved by exposing a dendrimer to a single generating compound capable of bonding to and tagging a deprotected but uncoupled termini. A signal generated by the signal generating compound to an otherwise uncoupled termini provides detection of the unreacted termini.

  • Patent number: 6566409
    Abstract: A lock unimolecular micelle includes at least one engineered acceptor specifically binding a ligand (or specifically a “key” unimolecular micelle) thereto. A key unimolecular micelle comprises a core molecule and a plurality of branches extending therefrom, at least one of the branches including a shank portion extending therefrom having a terminal moiety at an end thereof for binding to a complimentary acceptor of a lock unimolecular micelle. Together, the lock and key micelles form a unit, either irreversibly or reversibly bound wherein the lock micelles is a soluble receptor engineered to specifically bind to the specifically engineered key micelle.

  • Patent number: 5585457
    Abstract: Unimolecular micelies, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Each of the branches define a flexible arm from a central core atom and terminate with a hydrodynamic reactive group. A method is described for manipulating such cascade polymers.

  • Patent number: 5516810
    Abstract: Unimolecular micelles, generally referred to as cascade polymers, are constructed via the addition of successive layers, or tiers, of designed monomers, or building blocks, that possess a predetermined, branched superstructure consisting of connected physical matter inherently defining an internal void volume or void area within the molecular framework. Reactive sites located on the framework and hence within the void regions are capable of being chemically transformed to allow covalent and noncovalent incorporation of one or more guest species into the said void regions. Further, a method is described for making such cascade polymers that includes the steps of forming a unimolecular micelle containing internal void areas with accessible reactive sites capable of bonding to at least one guest after construction of the said unimolecular micelle. The guests are contained within the internal void volume of the cascade polymer and are available and accessible for additional chemical modification.
