Fig. 6.1 CD and ultraviolet (UV)-visible spectra of F3, F5, F7 and PF6 embedded in CTPC films
prepared from (a) THF and (b) DCM solutions, respectively. CPL and PL spectra of F3, F5, F7 and
PF6 embedded in CTPC film prepared from (c) THF and (d) DCM solutions, respectively. (e) The
g CPL values of PF6 embedded in CTPC film made from pure THF and DCM solvents, and THFDCM cosolvent as a function of volume fraction of THF. (f) Changes in the g CPL values monitored
at CPL wavelengths (λ ext ) from F3 (red), F5 (orange), F7 (green) and PF6 (blue) in CTPC films at
293 K on a quartz substrate under unpolarized light excitation. Excited at 345 nm for F3, 355 nm
for F5 and 360 nm for F7 and PF6. The raw data were obtained using a built-in program of the
JASCO CPL-200 spectrofluoro polarimeter and plotted as g CPL = g lum ellipticity (in mdeg)/[32,980/
ln10]/PL (DC in volts). Reproduced with permission from Guo et al. (2018)
