Project Description

Daron Janzen, Professor of Chemistry, received $7,500 from the APDC Grant fund to explore mechanochemical reactions to access Photoluminescent transition metal complexes. Photoluminescent metal complexes, materials that emit light, are used in a wide variety of applications including LEDs and sensors. Mechanochemistry involves performing chemical reactions by grinding reactants in the absence of solvent. This technique not only eliminates waste, but also can speed up results, increase yield, and provide access to products that cannot be obtained otherwise. Mechanochemistry is a technique that implements several features of Green Chemistry principles. Green Chemistry training and use in both the classroom and in research are a focus of the Chemistry department and build on the department's participation in the Green Chemistry Commitment. This project aims to develop mechanochemical methods to synthesize metal complexes of variable difficulty, optimize reaction conditions, and explore variables including grinding media and frequency of grinding. A careful comparison of mechanochemical and typical solution reactions using green chemistry parameters will help us develop a framework for opportunities and limitations of this synthetic method.
