From: Light-fueled transient supramolecular assemblies in water as fluorescence modulators
a Schematic illustrations of the light-induced AIE process of TCPE and the ACQ process of SRB. b Fluorescence emission of SMEH-TCPE, ASP-TCPE, SMEH-CS-TCPE, and ASP-CS-TCPE. Inset: emission of these solutions at 450 nm. c 3D fluorescence spectra of the light-induced AIE process from SMEH-CS-TCPE to ASP-CS-TCPE upon 420 nm irradiation over time. d 3D fluorescence spectra of the thermal dissociation process from ASP-CS-TCPE to SMEH-CS-TCPE over time. e, f CIE 1931 images of the light-induced AIE process and thermal dissociation process over time. Inset: fluorescence photographs of the two processes upon 365 nm UV light. g Fluorescence emission of SMEH-SRB, ASP-SRB, SMEH-CS-SRB, and ASP-CS-SRB. Inset: emission of these solutions at 583 nm and fluorescence photographs of (i) SMEH-CS-SRB and (ii) ASP-CS-SRB under 365 nm UV light. (λex = 325 nm solutions containing TCPE and λex = 560 nm solutions containing SRB unless mentioned. [SMEH]initial = 0.15 mM, [CS] = 40 μg/mL, [TCPE] = 0.01 mM, [SRB] = 0.001 mM, temperature: 25 °C, optical power density: 15 mW/cm2 unless mentioned).
