a Line integral curve of the GIWAXS patterns of the RDP films. b 19F NMR spectra of pure p-FCA and p-FCA mixed with PEABr. c FTIR spectra of pure PEABr, the control and target RDP film. TA spectra at various specific timescales of the d control and e target RDP film. The insert is the relative content of each phase in the RDP films. TA kinetics f at 404 nm and 438 nm of the control and g at 435 nm of the target RDP film
