Emission characterization of 1•3. a Emission spectra of 1, 3, complex 1•3 and complex 1•Brij S20 in water/MeOH (90:10, v/v) (1.00 mM for Brij S20 and 0.05 mM for other compounds). Inset: Emission color images of 1, 3, and complex 1•3 under 365 nm ultraviolet lamp. b Emission decay traces of the aerated (dark cyan line) and deaerated (red line) samples of complex 1•3, together with the deaerated sample of complex 1•Brij S20 in water/methanol (90:10, v/v) (1.00 mM for Brij S20 and 0.05 mM for other compounds)
