Solid State Anil Photochromism

Abstract We report in this paper on the work in photochromisn and thermochromism of anils in our laboratory and put this work in context with the past. Thus, results with anils containing a hetero-atom in the aniline ring, anils with the thenylamine moiety instead of aniline and anils with the CH2 grouping between the nitrogen in the bridge and the aniline or the thenylamine group are compared with those of N-salicylideneanilines.
