UV-Vis-NIR spectra for a pristine (gray), TBPA-PF6 (light blue), TBPA-SbCl6 (purple), and TBPA-TFSI (red) doped PBTTT thin films. Data were acquired (a) as doped and (b) after 88 h air exposure. c Ambient stability of conductivities of TBPA-PF6 (light blue), TBPA-SbCl6 (purple), and TBPA-TFSI (red) doped PBTTT thin films. Electrostatic potential map on molecular surfaces for ion pairs of (d). PBTTT/PF6, (e) PBTTT/SbCl6, and (f) PBTTT/TFSI, together with their space-filling, van der Waals-based representation. The calculations of these potentials were conducted with Spartan'16 software with the M06-2X functional and 6-31++G(d,p) basis set, where a pseudopotential is applied to the Sb atom.
