Fig. 3. (A) XRD patterns of air-dried AGP hydrogels (30 mM). (B) CD spectra of AGP1 assemblies (0.6 mM) in response to heat (70 °C) or UV irradiation (λ365 nm, 3.7 mW cm–2, 10 min). (C, E and G) CD/UV-Vis (black/red traces) spectra of AGP1, AGP2 or AGP3 assemblies (0.6 mM). (D and F) Switchable CD signals at 331 nm from AGP1 assemblies (0.6 mM) in response to temperature changes or alternating UV/Vis illumination. (H) CD spectra of AGP1 assemblies (0.6 mM) in response to host–guest chemistry by β-CyD (nβ-CyD : nAGP1 = 8 : 1) and ADA (nADA : nβ-CyD = 1 : 1).
