Electrical and spectrophotometric properties of charge transfer complexes of picric acid and some aniline derivatives

The prepared charge transfer complexes were investigated using infrared and nuclear magnetic resonance. It was proved that a proton transfer interaction takes place between PiOH and x-Ph.NH\+v\2\-v\ leading to the formation of PiO\+-\- and x-Ph.NH\+v\3\-v\++\- ions. The normal \#p\-\#p\ electronic interaction takes place by transferring an electron from the aniline ring to the picric acid. All complexes were proved to have a semiconducting character within the temperature range investigated. (Original abstract-amended)
