Observation of aggregation triggered by Resonance Energy Transfer (RET) induced intermolecular pairing force

Abstract In this report, we showed the existence of RET induced intermolecular pairing force by comparing their fluorescence behaviors under room illumination vs standing in dark area for either PFluAnt solution or PFluAnt&PFOBT mixture. Their prominent emission attenuation under room illuminati...
