Characterization methods accompanied to this dataset

Nuclear magnetic resonance (NMR)

All bottlebrush polymer ¹H NMR spectra were collected using a Varian Unity Inova AS600 600 MHz equipped with a 5 mm Varian triple resonance ¹H/¹³C/¹⁵N inverse detection probe with z-axis pulsed field gradient (PFG). All linear polymer ¹H NMR spectra were collected using a 600MHz SB Varian VNMRS equipped with a double resonance Broadband Probe Head 600 DB Auto X. Small molecule ¹H, ¹³C NMR, and 2D-NMR were collected using a Bruker Avance NEO 500 MHz equipped with a CryoProbe Prodigy BBO probe with z-axis PFG.

UV-Vis spectroscopy

Solutions: The targeted concentrations of polyelectrolytes were prepared using molarity defined by mols of charged repeating units (Q = 0.8 for SPEDOT and 0.6 for SP3HT and BPE). Absorbance of the solutions were measured through a Cary UV-Vis spectrophotometer (Agilent).

Solid samples for spectroscopy: PEDOT-3S-Na:BPE was extruded and smeared on top of a quartz substrate. The reflectance of the dried solid was measured through an UV3600 UV-Vis-NIR spectrometer (Shimadzu). The absorbance was calculated by the Kubelka-Munk transformation function of the diffuse reflectance spectra.

Rheology

A strain-controlled ARES-G2 rheometer equipped with an Advanced Peltier System (APS) and a solvent trap from TA Instruments was used to investigate the shear stress relaxation and linear viscoelastic properties of the blend. 8-mm stainless steel plates were used for all measurements. Pieces of paper soaked with water and THF were carefully placed inside the solvent trap to provide a saturated solvent environment to the material during testing to best minimize solvent evaporation. All measurements were done at room temperature using the same geometry and setup.

Grazing-incident wide angle X-ray scattering (GIWAXS)

Identical films for UV-Vis-NIR measurements were brought on beamline 11–3 at the Stanford Synchrotron Radiation Lightsource (SSRL). LaB6 was used as the calibrant for the beam center and a sample-to-detector distance of 315 mm was used. 2-D GIWAXS scattering images were collected using 2D Rayonix MX225 CCD area detector at an incidence angle of 0.10° with 30 s exposure times. The samples were kept under helium during X-ray exposure to minimize sample degradation and scattering from oxygen. The collected data was processed using Nika, a 2-D data reduction macro on Igor Pro using established procedures.
