Abstract :

Prof. Robin D. Rogers investigates in Separation Science, Green Chemistry, and Materials Science on all of the traditional fields of chemistry, including : a) inorganic chemistry : crystal engineering, polymorphism, synthesis of porous solids, complexation chemistry ; b) organic chemistry : synthesis of novel ionic liquids, polyethylene glycol resins, macrocyclic extractants and methodologies for utilizing biorenewable feedstocks ; c) analytical chemistry : liquid/liquid and solid/liquid separations, spectroscopy, and analysis of environmental contaminants ; d) physical chemistry : X-ray crystallography, solution spectroscopy, physical characterization of new materials and solvents, and empirical modeling of solvent properties ; e) biochemistry : biocatalysis in ionic liquids, incorporation of biomolecules in new cellulose-based materials, f) Materials science : development of new materials from cellulose utilizing ionic liquid technologies, and g) applied chemistry : development of new green technologies of industrial relevance.

Most of the research efforts are aimed to obviate the need for VOCs in separation and other chemical technologies by the development of alternative, environmentally benign (Green) solvent systems and by their selective application. Alternative solvent systems under active investigation include Ionic Liquids, Aqueous Biphasic Systems, Polyethylene Glycol (and other environmentally benign polymers), and Aqueous Biphasic Extraction Chromatographic Resins. Alternative technologies also include development of sol and other gel chemistries and the use of Crystal Engineering which can reduce the need for covalent derivatization in the production of functional materials.

Robin D. Rogers has had an influential role in the expansion of interest and research in ionic liquid systems. His initial paper on ionic liquid/aqueous partitioning (Chem. Commun. 1998, 1765) effectively kick-started interest in applying ionic liquids to clean separations. In 2005 he was awarded the Presidential Green Chemistry Challenge Award (Academic Division) for work related to the use of ionic liquids in sustainable technology. This technology was licensed later that year to BASF.
