Studies Conducted at National Autonomous University on Fullerenes Recently Reported

June 3, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Fullerenes is the subject of a report. According to news reporting originating in Mexico City, Mexico, by NewsRx journalists, research stated, "A series of pyrene-fullerene C-60 dyads bearing pyrene units (PyFC12, PyFPy, Py2FC12 and PyFN) were synthesized and characterized. Their optical properties were studied by absorption and fluorescence spectroscopies."

The news reporters obtained a quote from the research from National Autonomous University, "Dyads were designed in this way because the pyrene moeities act as light-harvesting molecules and are able to produce 'monomer' (PyFC12) or excimer emission (PyFPy, Py2FC12 and PyFN). The fluorescence spectra of the dyads exhibited a significant decrease in the amount of pyrene monomer and excimer emission, without the appearance of a new emission band due to fullerene C-60."

According to the news reporters, the research concluded: "The pyrene fluorescence quenching was found to be almost quantitative, ranging between 96%-99% depending on the construct, which is an indication that energy transfer occurred from one of the excited pyrene species to the fullerene C-60."
