(a) UV-vis absorption spectra of ARC (1 µM) upon gradual addition of DCP upto 1.1 equiv. in H2O-CH3CN (10:1, v/v). [Inset: left- UV-vis spectra of the region 200–400 nm, right- photograph of visual color changes of ARC and ARC + DCP complex in aqueous medium] (b) Fluorescence emission spectra (λex = 520 nm) of ARC (1 µM) toward DCP at varied concentrations (0, 0.01, 0.05, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50, 0.60, 0.70, 0.80, 0.90, 1.0, 1.05, 1.10 µM) in H2O-CH3CN (10:1, v/v). [Inset: Fluorescence color changes of ARC and ARC + DCP complex in aqueous medium].
