Combinatorial approaches to materials discovery.

Using a mixture of scientific intuition, iteration and serendipity, combinatorial materials science is an approach to the discovery and study of new materials that combines high-speed chemical synthesis, high-throughput screening and high-capacity information processing to create, analyse and interpret large numbers of new and diverse material compositions. Technology has now been developed that makes this powerful integration possible. The classes of materials under investigation include catalysts, luminescent, optical, magnetic and dielectric materials, and structural polymers.

Combinatorial Materials Science and Catalysis.

After forever changing the drug discovery process in the pharmaceutical industry, combinatorial chemistry methodologies are increasingly being applied to the discovery and optimization of more efficient catalysts and materials (see picture). With the advent of new combinatorial synthesis and screening technologies, coupled with integrated data management systems, the application of these technologies to materials science and catalyst research holds tremendous potential and brings high expectations to this new and exciting field.

A rare-earth phosphor containing one-dimensional chains identified through combinatorial methods

An unusual luminescent inorganic oxide, Sr2CeO4, was identified by parallel screening techniques from within a combinatorial library of more than 25,000 members prepared by automated thin-film synthesis. A bulk sample of single-phase Sr2CeO4 was prepared, and its structure, determined from powder x-ray diffraction data, reveals one-dimensional chains of edge-sharing CeO6 octahedra, with two terminal oxygen atoms per cerium center, that are isolated from one another by Sr2+ cations. The emission maximum at 485 nanometers appears blue-white and has a quantum yield of 0.48 +/- 0.02. The excited-state lifetime, electron spin resonance, magnetic susceptibility, and structural data all suggest that luminescence originates from a ligand-to-metal Ce4+ charge transfer.
