Fig. 2 — a Emission spectrum of TPE-PyT-CPS in acetonitrile/water mixtures with varied water fractions (ƒ_w). b Emission intensity plot of I/I₀ (dark dot) and the maximum emission wavelength (red dot) of TPE-PyT-CPS in different ƒ_w of the solvent mixture, I₀ represents the emission intensity in acetonitrile. c The particle sizes of TPE-PyT-CPS (10 μM) in water and acetonitrile was measured by dynamic light scattering. Inset: TEM images of TPE-PyT-CPS in water. Scale bar:1μm. Changes of UV-vis spectra of ABDA (60 μM) in the presence of TPE-PyT-CPS (10 μM) in acetonitrile (d) and water (e) under different durations of light irradiation (10 mW cm^-2). f The decomposition rates of ABDA in different solvents in the presence of TPE-PyT-CPS under light irradiation (A₀ and A represent the absorption of ABDA before and after laser irradiation, respectively). Experiments in 2a-f were performed two times independently and experiments in 2c (insert) were performed three times independently, representative images are shown.
