چکیده انگلیسی
Fluorescence (Förster) resonance energy transfer (FRET) from the phenyl groups of the non-ionic triton X-100 (TX-100) micelles to a potent bioactive molecule 3-acetyl-4-oxo-6,7-dihydro-12H-indolo-[2,3-a] quinolizine (AODIQ) has been studied using steady state absorption and fluorescence techniques. High values of Stern-Volmer constants (KSV) suggest that a long-range dipole-dipole interaction is operative for the energy transfer mechanism. From the analysis of the quenching of the donor fluorescence the energy transfer efficiency (E) has been determined in both premicellar and micellar environments. Experimental results reveal that the energy transfer process is more efficient in the micellar environment compared to the premicellar situation.
