Fig. 7. (a) UV-vis absorption and (b) fluorescence spectral changes (λex = 477 nm) of aggregated 10c (2.0 × 10−5 M) in DMSO/H2O (7 : 3, v/v) at room temperature with increasing concentration of DMAP and (c) UV-vis absorption spectral change of 10c in the presence of DMAP (6.0 × 10−2 M) in DMSO/H2O (7 : 3, v/v) with an increasing concentration of TFA, along with (d) photographs of these changes. (e) Schematic representation of the pH-responsive self-assembly of the boron-doped PAH 10c·DMAP adduct in aqueous media.
