This information is relevant in bio-electron transfer schemes and in emerging molecular electronics schemes such as storage of information using individual molecules. Our system consists of an inorganic cluster surrounded by dendritic ligands which act as an organic coating. Although the electrochemical and photophysical properties of a variety of metal clusters have been established, very little has been described on the chemistry on metal clusters.}, journal={MACROMOLECULAR SYMPOSIA}, author={Gorman, CB and Smith, JC and Sachdeva, R and Su, WY and Jiang, HW}, year={2000}, month={Jul}, pages={61–67} }

In this technique, care was taken to ensure complete structural equilibration by implementing a high temperature dynamics/simulated annealing protocol prior to evaluation of the molecular structure and dynamics. Both flexible and stiff repeat units that have been employed previously in the synthesis of dendrimers were considered. Flexible-unit dendrimers were found to be globular but not completely spherical. In contrast, stiff-unit dendrimers had a more eccentric, disk-like shape. For all dendrimers, the different generations within each molecule were found to be radially distributed throughout its interior. This appearance could be attributed to back-folding of some of the repeat units in the flexible case and to a branching angle effect in the stiff case. This distribution, however, did not preclude a molecular surface composed of a substantial portion of the topologically terminal groups.}, number={2}, journal={POLYMER}, author={Gorman, CB and Smith, JC}, year={2000}, month={Jan}, pages={675–683} }

Because they are dense, highly crosslinked, and chemically stable, diamond-like carbon (DLC) films and silicon oxide films (SiOx) were deposited on poly(ethylene terephthalate) by plasma-enhanced chemical vapor deposition to restrict polymer surface dynamics. In this study, the effects of ultrathin films on surface dynamics of these polymers were investigated. The layers were deposited on substrates with thickness below 100 Å. The thickness of films was measured with a scanning analyzer ellipsometer, while ATR-IR spectroscopy and Raman spectroscopy were performed to observe the chemical structure of the films. Films below 50 Å were also shown to be effective in stabilizing the plasma treated polymer surfaces. © 2000 John Wiley & Sons, Inc.

Heterogeneous electron-transfer rate constants indicated that the rigid series of dendrimers were more effective at attenuating the rate of electron transfer than were the flexible series of dendrimers. These results were rationalized using computationally derived models which indicated an offset and mobile iron−sulfur core in the flexible series of molecules and a more central and relatively immobile iron−sulfur core in the rigid series of molecules. Further consideration of these data indicated that, while the dendrimers containing rigid ligands had better encapsulated redox cores for a given molecular weight, these molecules had higher electron-transfer rates for a given molecular radius.}, number={43}, journal={JOURNAL OF THE AMERICAN CHEMICAL SOCIETY}, author={Gorman, CB and Smith, JC and Hager, MW and Parkhurst, BL and Sierzputowska-Gracz, H and Haney, CA}, year={1999}, month={Nov}, pages={9958–9966} }

The T 1 values of the phenyl and benzyl protons in the paramagnetic core dendrimers were attenuated compared to those of analogous protons in the diamagnetic core dendrimers. This observation indicated that protons in each set of topologically different repeat units (generation) of the dendrimer approach the core of the molecule closely in space. This conclusion is consistent with the computed radial density distributions of the different generations calculated from molecular dynamics simulations. In addition, by comparing T 1 values of protons at two slightly different temperatures, the terminal groups in both sets of dendrimers were concluded to be, on average, more mobile than the other generations within the dendrimers. This conclusion is consistent with the computed mean square displacement correlation functions for the different generations also calculated from molecular dynamics simulations.}, number={3}, journal={MACROMOLECULES}, author={Gorman, CB and Hager, MW and Parkhurst, BL and Smith, JC}, year={1998}, month={Feb}, pages={815–822} }
