Fig. 3. Self-assembly of CDI 4ab. (a) MeOH or NEt3 induced self-assembly of CDI and disaggregation with CHCl3 or heat. (b) UV-vis absorption spectra, normalised fluorescence spectra and quantum yields (Φ) of 4a in CHCl3 (λex = 450 nm) and MeOH (λex = 490 nm) at 10 µM concentration. (c) Changes in absorption spectrum of 4a (20 µM) in 9 : 1 NEt3 : CHCl3 upon heating. (d) The change of the 365 nm and 528 nm absorption peaks of 4a (20 µM) in (9 : 1 NEt3 : CHCl3) in as a function of temperature, fitted to an isodesmic model.
