Spectroscopic characterization of the photoinduced doping of methyl substituted polyaniline
- AT&T Bell Labs., Murray Hill, NJ (United States)
Poly(o-toluidine), methyl-substituted polyaniline, films have been doped by an acid generated by the irradiation of a non-metallic, non-ionic photoacid generator with UV light. The ultraviolet-visible and infrared spectra of the polymer obtained during photoinduced doping are similar to those obtained after doping with hydrochloric acid indicating that the changes produced in the chemical and electronic structures of the polymer are identical. Under the present conditions, it appears as though the photoinduced doping process is incomplete and hence result in films that are only slightly more conductive than the undoped samples. However, the photodoped samples are insoluble in solvents that dissolve the undoped polymer, allowing the use of this system as a negative photoresist that can be used to make transparent conductive patterns.
