Sean Naughton, Robyn Gaudet, and Annie Leslie co-author article in Chemical Physics Letters

Three 91直播视频undergraduate students, Sean Naughton (Biochemistry and Medical Biology 鈥13), Robyn Gaudet (Chemistry 鈥11) and Annie Leslie (Neuroscience 鈥13), are co-authors on an article recently published in the journal Chemical Physics Letters. The article 鈥淒irect Observation of Spiropyran Phosphorescence in Imidazolium Ionic Liquids鈥 is the result of work carried out in the laboratory of Amy Keirstead, Ph.D., an assistant professor in the Department of Chemistry and Physics.

The study describes the luminescence behavior of a novel 鈥渙n-off鈥 molecular switch (the spiropyran) in a series of ionic liquids, which are thought to be 鈥済reen鈥 alternatives to conventional solvents.  Specifically, the spiropyran was shown to emit both red fluorescence and blue-green phosphorescence in the ionic liquids compared to only fluorescence in molecular solvents, and it is the first reported example of spiropyran phosphorescence in ionic liquids. This type of system could be used to form a robust two-state-two-color emitting 鈥渟witch鈥 device for future nanotechnology applications.
