York University chemists have invented a new fluorescence-based method for accurately determining the strength of a range of Lewis acids, which could one day be used to help purify pharmaceutical drugs, improve industrial processes and explore next-generation technologies, according to a new chemistry study.

Measuring the Lewis acidity of molecular species is important because it allows chemists around the world to establish the utility of new compounds to facilitate chemical transformations for a range of applications. The team of six York University researchers developed a new method of testing for Lewis acidity using fluorescence, which is simpler, more accurate and more effective than the commonly-used Gutmann-Beckett method.

The finding, published today in the journal Chem, could lead to improved and cheaper processes for the pharmaceutical and chemical industries.

"The pharmaceutical industry is always looking for optimized processes to make new drugs and find new chemicals," said Thomas Baumgartner, professor in the Department of Chemistry, Faculty of Science, and Canada Research Chair in Organomain Group Materials. "Our method provides a valuable tool to help develop these processes," said Baumgartner, who co-led the study."
