Fig. 2. (A) Anodic cyclic voltammograms and (B) the oxidative-reduction ECL responses of the AIDF molecule (red line, f_w: 95%) and AIE molecule (blue line, f_w: 95%). (C) The oxidative-reduction ECL responses of the AIDF luminogen-modified GCE under the conditions of a potential window ranging from 0 V to 1.3 V (vs. Ag/AgCl), scan rate of 0.5 V s⁻¹, 0.1 M PBS containing 0.1 M KCl and 40 mM TPrA, and pH 7.44. PMT: 850 V. Inset: PL and ECL spectrum of the AIDF luminogen in the solid state (f_w: 95%). (D) PL and ECL trends of the AIDF luminogen with different f_w.
