Title: Polyoxovanadate-alkoxide clusters: Redox-active Scaffolds for the Multielectron Activation of Small Molecules
Abstract:  The development of alternative fuels from secure and sustainable resources is one the greatest environmental and economic challenge society faces today. To meet increased energy demands and mitigate rising atmospheric greenhouse gas levels, new carbon-neutral resources must be developed. The conversion of inert, abundant molecules, such as N2O and CO2, into chemical fuels (NH3 and CH3OH, respectively) represents an attractive solution, as energy is stored in chemical bonds of molecules that are easily transported as liquids. However, currently these fuels are produced through the activation of small molecules via heterogeneous processes conducted at extreme temperatures and pressures, requiring expensive, dedicated facilitiesResearch in the Matson Group focuses on using synthetic inorganic chemistry to address these issues related to energy storage and production. Toward accomplishing these goals, we are investigating the synthesis, characterization and reactivity of heterometallic polyoxovanadate-alkoxide clusters. These unique, multimetallic assemblies are generated in high yields via solvothermal reactions from simple molecular precursors. Notably, the polyoxovanadate subunit possesses a high degree of redox flexibility, rendering it ideal for supporting multielectron transformations of inert, gaseous substrates. Herein, we present our results related to the activation of small molecules across heterometal-functionalized polyoxovanadate-alkoxide clusters.

A surprisingly broad array of problems in modern materials chemistry relate to creating interfaces with two distinct, well-structured chemical environments at near-molecular scales. For instance, positioning nm-wide metal and semiconductor features with a pitch of 5-7 nm in a nonconductive matrix represents a central requirement for next-generation nanoelectronic devices.  Controlling interfacial chemical structure at scales from 5-10 nm is difficult using conventional lithographic patterning techniques. At the same time, a 6-nm pattern forms the cross-section of biological cell membranes, with distinct chemical environments created by a bilayer of phospholipids. We find powerful functions of phospholipid chemistry are preserved when the molecules are instead assembled in striped phases, in which the alkyl tails lie flat on a surface and the headgroups form 1-nm-wide stripes with a pitch of ~6 nm. We will discuss the relationship between structure and function at these interfaces, and useful material properties that emerge from the unusual surface chemistry; these include assembly of inorganic nanocrystals and crystallization of functional organic molecules.

 

 

Shelley Claridge received undergraduate degrees in mathematics and biochemistry from Texas A&M University, and subsequently worked as a software engineer for six years prior to completing a Ph.D. at UC Berkeley with Paul Alivisatos and Jean Fréchet. After a postdoctoral fellowship with Paul Weiss at UCLA, she joined the faculty at Purdue University in 2013. Her research at Purdue has been recognized with Young Investigator awards from NSF, DARPA, 3M, and DuPont (one of 8 globally), and received emerging investigator recognitions from Journal of the American Chemical Society, Chemical Communications, Analytical Methods, and Analytical and Bioanalytical Chemistry.
