Abstract
Perylene fluorescence was found to be quenched by CO2+ and Ni2+ ions b elow the phase transition in small unilamellar vesicles. Long-range Fo rster dipole-dipole energy transfer was found to describe the quenchin g of the perylene fluorescence in the case of Co2+ whereas for Ni2+ th e quenching mechanism was found to be more akin to the shorter range D exter exchange interaction. A Co2+ sensor in solution based on Forster energy transfer from Perylene is proposed.
