a, Control. b, Target. Key peaks from MFAI (2.78 ppm) and DMFAI (2.94 ppm) are highlighted. Spectra were recorded every 15 min in a mixture of d6-DMSO:d7-DMF with the ratio used for PSC fabrication and the intensity is normalized to the residual solvent peak (*). c, Mechanism of the [Bcmim]Cl-mediated stabilization of the PPS.
