Figure 4

(a) UV–vis spectra of 2 at different temperatures (decalin, cT = 10 μM). (b) Plot of the variation of the absorbance measured at 519 nm versus cooling at 1 °C min–1. Red curves correspond to the fitting to the EQ model. (c) PL spectra of (S)-2 in MCH, toluene, and CHCl3 (λexc = 380 nm, 298 K). The inset shows pictures of the solutions of (S)-2 in MCH, Tol, and CHCl3 used to register the PL spectra without (top samples) and with illumination (bottom samples). (d) AFM image and (e) height profile along the green line in (d) of the supramolecular polymers formed by (R)-2 in MCH onto HOPG (spin coating; cT = 10 μM, 298 K).
