The Dolbier research program is dedicated mainly to the synthesis and study of compounds containing fluorine. Organic compounds that contain fluorine are of vital interest and importance to virtually every area of modern technology, including polymers, pharmaceutical/agrochemical products, and material science. Because of the special synthetic challenges that it presents, and because of the unique structure/reactivity relationships observed for fluorine-containing compounds, the field of organofluorine chemistry is one of both fundamental and practical interest. In our case this is reflected by the projects in the group, which are a mixture of fundamental and applied projects. Although we remain interested in the fundamental aspects of reactivity of fluorinated molecules and reactive intermediates, our major research interests now involve the development of new synthetic methods for incorporation of fluorine into organic molecules, mainly through the invention and development of new fluorinated “building blocks.”

Research in our group is devoted to using special mass spectrometric techniques to study the reactivity and properties of many different ionic systems in the gas phase – from atoms to antibodies. While our work is strongly based in physical chemistry, we have collaborated heavily with inorganic, organic, and analytical chemists in the past, and will continue to work with them and the members of the Department’s biochemistry division in the future. Almost all of our experiments use one of three Fourier transform ion cyclotron resonance (FTICR) mass spectrometers to form and trap ions for reactivity and spectroscopy studies, as well as to carry out mass analysis.
Many of our current research projects use electrospray ionization (ESI) to transport pre-formed ions from solution into the gas phase for mass spectrometric analysis. The ions in solution range from atomic ions, for elemental analysis and speciation studies, to doubly- or triply-charged organic and inorganic species, to very large multiply-protonated biomolecules such as proteins and nucleic acids. With special care, one or more solvent molecules can be left attached to the ions when they enter the FTICR mass spectrometer, thus allowing the effect of solvation on reactivity or other ion properties, such as spectra, to be studied.

Our research deals with theoretical and computational aspects of molecular and materials sciences, with emphasis on the unified treatment of physical and chemical kinetics using quantum molecular dynamics. It includes collision-induced and photoinduced phenomena in the gas phase, clusters, and at solid surfaces. Our aim is to provide a fundamental approach to molecular dynamics, where electronic and nuclear motions are consistently coupled to account for quantal effects. We use quantum and statistical mechanics, mathematical, and computational methods, to describe time-dependent phenomena (such as femtosecond dynamics and spectra) in both simple and complex molecular systems.

There is growing evidence that the molecules necessary for the evolution of life on earth arrived here from the interstellar medium. The study of these molecules is therefore one of great current interest. To date, over one hundred and twenty molecules have been found to exist in interstellar space. Most of these molecules have been detected by radioastronomy, but others have been found by visible/ultraviolet or infrared spectroscopy. There are two major types of signals from interstellar space that have intrigued and puzzled astronomers, astrophysicists, and astrochemists. They are the so-called “unidentified” interstellar infrared emission bands (UIRs) and the diffuse interstellar absorption bands (DIBs). Both have been known for many years, the former for about 30 years and the latter for about 80 years, but the species responsible for them have not yet been found, despite much research. Early on, the thought was that the carriers of these bands were small grains, but, in recent times, it has been agreed that a gas phase molecule-like species is more likely. The conditions under which these molecular species must survive are stark. Temperatures can be extremely cold (10-100K) except, of course, near stars. Pressures are generally lower than any produced here on earth. And the radiation present can run the gamut from microwaves to X-rays and beyond.

Research in our lab is focused on the interaction of light with organic and organometallic materials. We have an interest in a number of optical applications such as light emitting devices (LEDs), fluorescent sensors, solar energy conversion and non-linear optical phenomena. In one specific project we are involved in the chemical synthesis and fundamental study of water soluble conjugated polymers (conjugated polyelectrolytes). These materials find application in a number of areas, including fabrication of fluorescent bio-sensors and nano-structured films for use in organic photovoltaic cells. In another line of investigation, we are studying the optical properties of novel conjugated organometallic oligomers and polymers. Finally, we have a long standing interest in the development of thin film based luminescent oxygen sensor materials which are used by aerodynamic engineers to measure air pressure distributions on wind-tunnel models.

During the 1960s, we were world leaders in developing atomic fluorescence spectroscopy and phosphorimetry for trace analysis. During the 1960s and 1970s, we were world leaders in using signal-to-noise calculations and measurements to optimize atomic and molecular spectrometric methods. In the 1970s to the present, we have been world leaders in the use of lasers in atomic fluorescence spectrometry, atomic emission breakdown spectroscopy, Raman spectrometry and molecular luminescence spectrometry.
Our research in the past 5 years has been mainly directed towards several unique developments, including the modeling and applications of laser induced plasmas produced in aerosols, on solids, and in liquids. These studies involve measurements of the emission characteristics of various laser plasmas and application of physical principles to obtain fundamental information, including plasma temperatures, species number densities, and line broadening. Our applications of laser plasmas have been applied to both mineral samples as well as organic materials in order to obtain both quantitative results as well as composition. The other current major project involves the development of an imager based upon either resonance ionization or fluorescence of either mercury or cesium atoms in a specially designed cell. This study has involved fundamental spectroscopy studies of Hg and Cs. The imager will detect RayLEI scatter, Raman scatter, and fluorescence and will be used for a number of applications including imaging of skin diseases, varicose veins, arterial blockage of arteries, as well as moving and vibrating objects, such as materials in an assembly line. Although these two major current projects are not the only ones in progress, they demonstrate the current excitement and effort in my research group. Research in the Winefordner group involves a direct collaborative interaction with Professor Nicolo Omenetto and Dr. Ben Smith.
