Assemblies in presence of light (films, 293 K). a) FTIR absorption spectra of films obtained by drop coasting of irradiated solutions of TATA‐C12 at 2.3 mM in CHCl₃ (0–24 min), Zoom on the N−H region (left) and C=O regions (right). Arrows serve as a guide to the eyes for the evolution of the main bands upon increasing the irradiation time. b) UV‐Vis‐NIR absorption of films obtained by drop coasting of irradiated solutions of TATA‐C12 at 2.3 mM in CHCl₃ (0–24 min). Arrows serve as a guide to the eyes for the evolution of the main bands upon increasing the irradiation time. Inset: zoom on the 200–250 nm region. Analyses are normalized to the absorbance at 323 nm. c) EPR spectra of films obtained by drop coasting of irradiated solutions of TATA‐C12 at 2.3 mM in CHCl₃ (0–24 min).
