Fig. 2. Emission spectra of the solutions or suspensions containing (A) PF-TFQ-BODIPY, (B) TPE-TFQ-BODIPY, and (C) Pttc-TFQ-BODIPY polymers in THF/water mixtures with different volumetric fractions of water (fw, vol%). (D) Response of BODIPY fluorescence intensities (∼724 nm) for the three polymers in mixed solvents of THF/water (water fraction, v/v%). Normalized absorption spectra of (E) PF-TFQ-BODIPY, (F) TPE-TFQ-BODIPY, and (G) Pttc-TFQ-BODIPY in pure CH₂Cl₂ (black lines), Pdot aqueous form (green lines), and film form (red lines).
