a, b Temperature-dependent PL spectra with excitation wavelength at 455 nm and c extracted exciton binding energies of BTBpy and TpBpy. AFM images in surface potential mode for d BTBpy and e TpBpy under light illumination. f, g Two surface potential profiles along the lines in (d, BTBpy) and (e, TpBpy) under dark and light, respectively. h Photocurrent response and i EIS spectra of BTBpy and TpBpy.
