Visualizing Material Processing via Photoexcitation-Controlled Organic-Phase Aggregation-Induced Emission

Figure 3

Mechanism study: continuous enhancement of emission and absorption spectra of (a) H, (b) PH, and (c) PH-b-PG in 1,4-dioxane with prolonged irradiation duration. The insert shows the corresponding photographs before and after irradiation under a UV lamp. The absorption and absorption intensity at 410 nm of DPBF in the presence of (d) H and (e) PTOEP versus the UV irradiation time for monitoring the singlet-oxygen formation and the triplet-state behavior. (f) Calculated geometry of the ground ( state) and excited states ( and states) of H.
