Synthesis and carbon-13 NMR studies of liquid crystals.
(2000)
Eight series of liquid crystals containing an electron-donating group at one end of a conjugated system and an electron-withdrawing group at the other end have been synthesized. The electron-donating group is 4- ...
Ferrocene-Modified Linear Poly(ethylenimine) Bioelectrode Materials for Use in Glucose/O2 Biofuel Cells
(2014-04-21)
Tetramethylferrocene-modified linear(polyethylenimine) (FcMe4-C3-LPEI) was cross-linked with ethylene glycol diglycidyl ether (EGDGE) in the presence of glucose oxidase (GOx) on carbon electrodes to form enzymatic redox ...
Synthesis, structure and electrochemical performance of poly(ethylenimine)-based electrolytes.
(2004)
Ion conducting polymers have found application as the electrolyte host in lithium batteries and proton exchange membrane fuel cells as a result of desirable processing and adequate ionic conductivity. Poly(ethylenimine) ...
Polyamine-based polymer electrolyte modification and performance.
(2005)
Finally, lithium secondary batteries that function at room temperature were built using LPAG2EI based SPE and recycled at different temperatures and drain rates for preliminary evaluation. Although the recycling results ...
Synthesis and spectroscopic studies of polymer electrolyte hosts: Linear poly(ethylenimine), linear poly(N-methylethylenimine) and linear poly(N-2-(2-methoxyethoxy)ethylethylenimine).
(2002)
Three topics that are of interest to scientists in polymer electrolytes are: (1) ion-ion interactions; (2) ion-polymer interactions; and (3) how these interactions correlate to ionic conductivity. A spectroscopic study of ...
The synthesis of group IV metallocene dichlorides with variable sterics, conformational mobility and geometric shapes.
(1997)
New chiral doubly bridged bis(tetrahydroindenyl)zirconium dichloride 285 has been synthesized from chiral doubly bridged 284 in excellent yield. These complexes give access to rigid ansa-bis(indenyl)- and ansa-bis(tetrah ...
The stereochemistry and mechanism of the iron pentacarbonyl-promoted coupling of strained olefins to carbon monoxide :
(1985)
The stereochemistry and mechanism of the iron pentacarbonyl-induced coupling of strained olefins (e.g., 7-phenylnorbornadiene) to carbon monoxide is discussed. Emphasis is placed on determination of the structure of one ...
Unique ansa-bis(indenyl)metallocene dichlorides: The quest for catalysts.
(2003)
The background, methodology, design, and synthesis of these four metallocenes will be discussed. In addition, other less successful attempts will be discussed as regards limits to this new methodology.
Copper catalyzed cyclopropanation using chiral [2.2]paracyclophane ligands and activation of naphthalenes toward catalytic hydrogenation by coordination of metal moieties.
(1999)
The coordination of an iron cyclopentadienyl cation to the naphthalene moiety resulted in activation of the naphthalene ligand toward catalytic hydrogenation. Napthalene, and several dimethylnaphthalenes, when coordinated ...
I. AN INVESTIGATION INTO THE NATURAL PRODUCTS CHEMISTRY OF THE SOFT CORAL ASTEROSPICULARIA RANDALLI. II. AN INVESTIGATION INTO THE NATURAL PRODUCTS CHEMISTRY OF THE NUDIBRANCH TRIDACHIA CRISPATA. III. STRUCTURE DETERMINATION OF THE 11BETA, 12BETA-EPOXYPUKALIDE FROM THE GORGONIAN LEPTOGORGIA SETACEA.
(1984)
Chapter 1 deals with the twenty-eight compounds which have been isolated from the soft coral Asterospicularia randalli, collected in May 1979 and April 1983 at Guam Island in the Pacific. Seven of the twenty-eight natural ...
