Fluorescent organic aggregates (FOAs) of CS-1 have been used for the fluorescence based selective estimation of ClO4- ions. CS-1 undergoes self-aggregation to form FOAs ( phi = 0.35) with a diameter of 140 plus or minus 50 nm in aqueous medium. Dynamic light scattering and field emission scanning el...
