H NMR spectra of the synthesized polymers: (a), 6F-HAB; (b), 6F-HAB-CI; (c), 6F-
HAB-ETCOU.
3.2. Photoreactivity and photoalignment
Figure 3 shows UV absorption spectra of the photosensitive polymer films irradi-
ated with the unpolarized UV light of 260-380 nm wavelength at varying expo-
sure dose. 6F-HAB-CI polymer exhibits an absorption maximum at 278 nm
