Figure 1. (A) UV-vis absorption spectra of TPE-Py-I with the gradual addition of CB[8]; (B) Fluorescence emission spectra (λ_ex = 384 nm) of TPE-Py-I with the gradual addition of CB[8]; the inset was the fluorescence images of TPE-Py-I (left) and 2TPE-Py-I@CB[8] (right); (C) Job’s plot of TPE-Py-I and CB[8]; (D) DLS of 2TPE-Py-I@CB[8], the inset was Tyndall effect of 2TPE-Py-I@CB[8]; Zeta potential of (E) TPE-Py-I and (F) 2TPE-Py-I@CB[8]. (Experimental conditions: TPE-Py-I = 10 μM, CB[8] = 5 μM, room temperature.) UV-vis: Ultraviolet-visible; TPE: tetraphenylethylene; DLS: dynamic light scattering.
