  • Patent number: 7198771
    Abstract: The invention comprises a chemical composition with the structure shown below. The composition can be polymerized or pyrolyzed, forming transition metal nanoparticles homogeneously dispersed in a thermoset or carbon composition. The size of the nanoparticles can be controlled by manipulating the number and arrangement of functional groups in the composition and by changing the conditions of the polymerization or pyrolysis. The resulting thermosets and carbon compositions have useful magnetic, electric, mechanical, catalytic and/or optical properties.

  • Patent number: 7196210
    Abstract: The ability to design and construct solid-state materials with pre-determined structures is a grand challenge in chemistry. An inventive strategy based on reticulating metal ions and organic carboxylate links into extended networks has been advanced to a point that has allowed the design of porous structures in which pore size and functionality can be varied systematically. MOF-5, a prototype of a new class of porous materials and one that is constructed from octahedral Zn—O—C clusters and benzene links, was used to demonstrate that its 3-D porous system can be functionalized with the organic groups, —Br, —NH2, —OC3H7, —OC5H11, —H4C2, and —H4C4, and its pore size expanded with the long molecular struts biphenyl, tetrahydropyrene, pyrene, and terphenyl.

  • Patent number: 7157592
    Abstract: A method for producing ferrocene and other organometallic compounds of cyclopentadiene is disclosed. Dry iron chloride (or other selected metal salt) is added to a solution of cyclopentadiene, diethylamine, potassium and dibenzo-18-crown-6 ether in a cooled flask under a dry nitrogen atmosphere. The solution is mixed vigorously for a few hours and any excess diethylamine is evaporated. Ferrocene (or other organometallic compounds of cyclopentadiene) is extracted from the residue using petroleum ether, and any solvent is removed.
