Figure S4. Progressive changes in the emission of a CHCl3−exposed 0.05 wt.% TPAP/PC
film (after its equilibration in the presence of CHCl3 vapors) as a function of CHCl3
desorption (λexc = 325 nm). TPAP/PC film thickness = 80 µm. The spectra were collected for
25 min with a time interval of 1 min and normalized at the emission maximum after 25 min
of exposure.
