PROFESSIONAL EXPERIENCE

Dr. Christe has 55 years of experience in the synthesis of novel high energy oxidizers, explosives and rocket propellants and has managed and scientifically directed many government funded research contracts. He has achieved the first syntheses of many spectacular compounds, such as ClF3O, ClF3O2, halogen perchlorates, OIF4OF, OsF4O2, and ions, such as NF4+, ClF6+, ClF6-, ClO2F2-, ClO2F2+, ClF2O+, ClF4O-, NF3+, NF2O+, N7O+, and NH2F2+. He has invented solid propellant fluorine and hydrogen gas generators for chemical laser weapon systems and has discovered the first purely chemical synthesis of elemental fluorine. He has developed a synthesis for anhydrous tetramethylammonium fluoride and has pioneered the use of this compound as a source of “naked” fluoride ions, which has led to a renaissance of high coordination number chemistry. Among the novel compounds, which he prepared in this manner, are the XeF5- and IF52- anions, which are the first known examples of pentagonal planar AX5 species. His most recent breakthrough discovery in fluorine chemistry is based on the realization that strong Lewis acids can enhance the oxidizing power of fluorine by 6.7 eV, making it the strongest known neutral one-electron oxidizer. His seminal work in fluorine chemistry has received world-wide recognition, resulting in Wikipedia referring to him as the “Fluorine God.” In addition to his impressive achievements in fluorine chemistry, he also has made important contributions to numerous other fields of chemistry. For example, he has prepared the first stable oxonium, OH3+, and sulfonium, SH3+, salts, has discovered a new process for metal joining using hydrazine as a gaseous flux, has developed new methods for the introduction of fluorine into aromatic rings, and has pioneered graphite based ion exchange resins for the use with powerful oxidizers in anhydrous HF solutions. In addition, he has made major discoveries in the field of the chemistry of fluorocarbons, inorganic high polymers, chemical laser technology, and methane oxychlorination. More recently, he has focused his efforts on polynitrogen chemistry and has discovered the N5+, N3NFO+, N7O+, and cyclo-N5- ions, nitrylcyanide, and many new polyazides and polycyanides. His latest research interests are in the areas of high oxygen carriers and green replacements for ammonium perchlorate, liquid monopropellants and explosives. He has made extensive use of computational chemistry and, together with Dave Dixon, he has also invented the first quantitative scales for oxidizer strength and Lewis acidity. The latter compliments the pH scale and will become equally important in chemistry.
