The main goal of this project is to use synthetic molecular clusters as building blocks to assemble a new class of multi-dimensional coordination solids.
Christopher Bejger (CHEM)
We will design and synthesize framework materials comprised of metal chalcogenide clusters (MCCs) linked by organic ligands. Synthetic analogues to traditional transition metal dichalcogenides (TMDC) using molecular precursors are needed to prepare functional materials by design. Incorporating nanometer sized MCCs, which we call “superatoms”, into new frameworks will allow for rational modification and new materials with applications in nanoelectronics, optoelectronics, and catalysis.
REU Students’ Role
The students in Dr. Bejger’s lab will learn how to synthesize molecular clusters and phosphine ligands using air free inorganic synthetic techniques. These molecules will be used as precursors for synthesizing framework materials. The new compounds will be characterized using nuclear magnetic resonance and absorbance spectroscopies, and electrochemical methods. New frameworks will be characterized using X-ray diffraction. In addition, the charge transport and magnetic properties of the materials will be studied.
