Photophysical And Photochemical Investigations Of New Tunable Luminescent Metal-Metal Bonded D8-D10 Exciplexes, Howard H. Patterson Sep 2011

Photophysical And Photochemical Investigations Of New Tunable Luminescent Metal-Metal Bonded D8-D10 Exciplexes, Howard H. Patterson

University of Maine Office of Research Administration: Grant Reports

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports Dr. Howard Patterson at the University of Maine at Orono to investigate d8-d10 exciplexes exhibiting multiple excimeric emissions that can be tuned across the UV and visible regions by: site-selective excitation, temperature, varying the concentration in solution or the solid state (alkali halide hosts), and/or controlled laser irradiation that leads to reversible write/read/erase changes. Photophysical, photochemical, and computational studies will be performed in order to assess the factors that are important for establishing structure-luminescence relationships in tunable systems. The broad tunability previously observed in d10-d10 complexes will be extended …


Metallophilic Interactions In Closed-Shell Metal-Metal Bonded Luminescent Systems And Their Tunability For Excited State Energy Transfer, Howard H. Patterson Apr 2009

Metallophilic Interactions In Closed-Shell Metal-Metal Bonded Luminescent Systems And Their Tunability For Excited State Energy Transfer, Howard H. Patterson

University of Maine Office of Research Administration: Grant Reports

Howard Patterson, University of Maine, is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for photochemical studies of metal-metal bonded excimers and exciplexes. In solution or in the solid state, dicyanoaurate(I) and dicyanoargentate(I) ions oligomerize. The oligomers show complex photochemistry, including luminescence caused by metallophilic interactions. These systems can be tuned over 18,000 wavenumbers by doping or by adding various donor ions. This research project will look in detail at lifetime and time-resolved studies, vibrational analysis by Raman scattering and infrared, structural studies by x-ray and neutron diffraction, and theoretical analyses. The research will provide insight into metallophilic interactions …


U.S.-Russia Cooperative Research: Designing Gold(I) Complexes For New Materials, Alice E. Bruce, Mitchell Bruce, Dmitri Lemenosvsii, Victor Dyadchenko, Feb 2005

U.S.-Russia Cooperative Research: Designing Gold(I) Complexes For New Materials, Alice E. Bruce, Mitchell Bruce, Dmitri Lemenosvsii, Victor Dyadchenko,

University of Maine Office of Research Administration: Grant Reports

This award in International Programs and the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports collaborative research by Dr. Alice E. Bruce of the University of Maine and Dr. Dmitri Lemenovskii of Moscow State University (Russia). The goal of the project is to design gold complexes that will be useful in new materials, such as liquid crystals. Organogold compounds containing rod-shaped molecules will be synthesized and structurally characterized. Lattice effects in liquid and solid phases formed from the compounds will be studied. Both groups are experienced in the synthetic aspects of the research, but will take advantage of the University of …
