A study on the fluorescence quenching of 9-Aminoacridine by certain antioxidants

► 9-Aminoacridine forms ground state complex with antioxidants. ► Lifetime measurements support the static quenching mechanism. ► Binding constant and number of binding sites were calculated. ► Rehm-Weller equation confirms the electron transfer process. ► The results will have great importance in pharmacy, pharmacology and biochemistry.
