Abstract:
The decay of pyrene in the presence of excimers in small unilamellar vesicles of 3-sn-phosphatidyl glycerol, dipalmitoyl and 3-sn-phosphatidylglycerol from egg yolk has been analyzed with the use of models appropriate for reactions in restricted geometries. Results are presented with emphasis on probe concentration and temperature. The reaction rate in an organized lipid phase is redefined in a simple manner which allows for a simple treatment of any reaction in such environments. The analysis allows detection of pyrene aggregation in the vesicle lipidic core.
