In applications that use a single quantum dot, such as biological sensors, this fallibility can have dramatic consequences. Quantum dots are generally brighter and longer-lived than organic dyes used today, and are increasingly used in biology to tag biomolecules. Once tagged, the dot’s emissions will act as a beacon for scientists, allowing them to track the target biomolecule. But if a dot blinks, scientists may lose track of their biomolecule. It’s like trying to radio-track wolves with capricious transmitters that could cease transmitting at any moment.

University of Toronto materials science and engineering (MSE) researchers have demonstrated for the first time the key mechanism behind how energy levels align in a critical group of advanced materials. This discovery is a significant breakthrough in the development of sustainable technologies such as dye-sensitized solar cells and organic light-emitting diodes (OLEDs).

Researchers often work with a narrow range of compounds when making organic electronics, such as solar panels, light emitting diodes and transistors. Professor Tim Bender and Ph.D. Candidate Graham Morse of U of T’s Department of Chemical Engineering and Applied Chemistry have uncovered compounds that exhibit unique and novel electro-chemical properties.
