  • Research supported by the Department of Energy focused on the development of molecular and semiconductor based approaches to the conversion of light to electricity or fuels. Studies of molecular systems included the preparation and characterization of new molecules which could serve as light absorbers and/or as elements that bring about charge separation following photoexcitation. Ring-opening metathesis polymerization, in particular, was demonstrated to be useful in preparing new functional polymers of importance in developing fundamental understanding of the excited state dynamics of multicomponent polymers for light absorption and charge separation. Charge separation and ultimate collection is essential to the development ofmore » efficient systems for the conversion of light to electricity or fuel. Molecular materials such as poly(p-phenylene-ethynylene)s represent possible semiconductor photovoltaic materials that can be both efficient and low cost. Study of the optical and electrical characteristics and excited state behavior of such new materials contributed to an understanding of the design parameters needed for efficient photovoltaic devices based on such materials. Approaches to functionalization of electrode, including photoelectrode, surfaces for the purpose of improving interface energetics and kinetics in photoelectrochemical devices show that a wide range of molecular chemistry can be applied to tailoring the properties of electrode/electrolyte interfaces.« less

    The goal of this research is the study of the propagation of very high frequency sound waves in amorphous materials and liquids in order to achieve a better fundamental understanding of how heat flows in these materials.

  • Research efforts were concentrated on developing the tandem magnetic sector (EB)/reflection-time-of-flight (TOF) instrument, preliminary experiments with tandem TOF/TOF instruments, developing method for performing photodissociation with pulsed lasers, experiments with laser ionization of aerosol particles, matrix-assisted laser desorption ionization (MALDI), and ion-molecule reaction chemistry of ground and excited state transition metal ions. This progress report is divided into: photodissociation, MALDI (including aerosols), and ion chemistry fundamentals.

    Methods were devised for preparing cryptands (bicyclic ligands). Effects of addition of hydrophobic side chains on crown ethers used in separation systems; crowns containing side chains of varying lengths were studied in back extraction and dual module hollow fiber membrane separation experiments. Thermodynamics of macrocycle-cation reactions were studied at high temperature. Effort was made on computer (molecular mechanics) modeling of macrocycle binding of alkali metal ions in gas phase. 8 figs, 26 refs.

  • A method was developed for synthesizing a new complex for studying C-H activation, (HBPz*{sub 3})Rh(CNCH{sub 2}CMe{sub 3})(PhN=C=NCH{sub 2}CMe{sub 3}). This complex loses the carbodiimide ligand, thereby serving as a precursor for a 16-electron Rh(I) fragment which activates (via oxidative addition) a wide range of aromatic and aliphatic C-H bonds. Mechanism of activation of benzene by this fragment was studied. Reaction of [Tp`Rh(CNR)] fragment with aliphatic hydrocarbons was also studied. A study of C-H bond activation by the complex MnH{sub 3}(dmpe){sub 2} was completed. Reactions of [Ru(dmpe){sub 2}] with several small molecules were also investigated. Effects of fluorine substituents on aromaticmore » ring on C-H activation were looked at. Studies of {eta}{sup 2}-arene coordination with [(C{sub 5}Me{sub 5})Rh(PMe{sub 3})] were completed; studies of reaction of this complex with 1,3-disubstituted benzenes are in progress.« less
