The obtained results are based on time-resolved electronic energy transfer from donors (2-(9-anthroyloxy)-stearic acid) localised in the lipid-water interface to acceptors BnPC (n = 3, 5, 7, 9, 11, 13, 15), as well as the energy migration among the Me4-BODIPY groups of BnPC:s. The donor-acceptor and the donor-donor experiments strongly suggest that the Me4-BODIPY group in BnPC tends to loop back close to the lipid-water interface. The Me4-BODIPY groups, residing in the two bilayer leaflets, are located at approximately the same depth, and transversally separated by ca. 27 angstrom for all n-values.
