a Transient photocurrent responses and (b) EIS Nyquist plots of S-TFPT, PtNPs@S-TFPT, and PtSA@S-TFPT. c PL spectra of S-TFPT, PtNPs@S-TFPT, and PtSA@S-TFPT, excited at 417 nm. Calculated HOMO (d, f, h) and LUMO (e, g, i) distributions for the model molecules: S-TFPT (d, e), PtNPs@S-TFPT (f, g), and PtSA@S-TFPT (h, i). (The yellow region indicates charge accumulation, while the cyan region indicates charge depletion. Isosurface value is 4 × 10−9 e/Bohr3).
