Abstract
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-12 H-indolo-[2,3- a] quinolizine (AODIQ) has been studied using steady state absorption and fluorescence techniques. High values of Stern–Volmer constants ( K SV) 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.
