A, Letsinger, R. With single-molecules as researched in molecular electronics at the 5 nanometer scale this would be impractical. Data storage has been accomplished by the use of molecular switches with photochromic and photoisomerizable units, by electrochromic and redox -switchable units, and even by molecular motion. Addadi, L. The work described in this review has been supported by the Chemical Sciences program of the Office of Basic Energy Sciences of the Department of Energy. Some non-covalent interactions may exist between the different components often those that were utilized in the construction of the systembut covalent bonds do not.
Fritz, M. Meijer Chemical Communications, 26- Abstract 3 Towards supramolecular electronics A. Wong, K. Those interested in attending both meetings must submit an application for the GRC in addition to an application for the GRS. Supramolecular metallocycles are macrocyclic aggregates with metal ions in the ring, often formed from angular and linear modules. Guo, S.
In its simplest form, imprinting utilizes only steric interactions, but more complex systems also incorporate hydrogen bonding and other interactions to improve binding strength and specificity. Yang, J. The cylindrical assemblies possess internal helical order and self-organize into columnar liquid crystalline lattices. A, Crooks, R. Commun, The directionality, reversibility, and strong bonding nature of hydrogen bond make it an attractive and useful approach in supramolecular assembly.

Watzke, H. Fraser Stoddart and Bernard L. Venue and Travel Information Conference Description The Gordon Research Seminar on Electron Donor-Acceptor Interactions is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas.
Template-directed synthesis is a special case of supramolecular catalysis. In this work, to view chlorophyll Chl —zeaxanthin Zea excitation energy transfer EET and charge transfer CT as possible NPQ mechanisms, we performed transient absorption TA spectroscopy on live cells of the microalga Nannochloropsis oceanica.

Metal ions are frequently used for assembly of large supramolecular structures. Bagshaw, S. These include systems based on supramolecular assembly of peptides, host—guest macrocycles, high-affinity hydrogen bonding, and metal—ligand interactions. Non-covalent interactions are extremely important in catalysis, binding reactants into conformations suitable for reaction and lowering the transition state energy of reaction.
In supramolecular electronics, assemblies of pi-conjugated systems on the 5 to nanometer length scale are prepared by molecular self-assembly with the aim to fit these structures between electrodes.
Work in our laboratories has focused on both aspects of this problem. Bigham, S. Garcia, M. Kimizuka, T. Evans-Gowing, R.

Photoinduced electron transfer in supramolecular ruthenium–porphyrin assemblies The optoelectronic properties of the assemblies and the electronic interactions between the chromophoric units have been comprehensively characterized by computational investigations, and steady-state and time-resolved emission spectroscopy.
Photoinduced. Ion binding often mediates electron transfer in bio logical systems as a cofactor strategy, either as a promoter or as an inhibitor. However, it has rarely, if ever, been exploited for that purpose in synthetic host-guest assemblies.
We report here that strong binding of specific anions (chloride, bromide, and. Professor Jason J Davis. Email: [email protected] Visit Personal Site.
