A series of ferrocenylaldimines (Fc-CH=N-R) were prepared by Schiff base condensation of formylferrocene with polyacenylamines RNH2 where R = Naphtyhl ,5,6,7,8-tetrahydronaphthyl, anthyl, and pyrenyl groups, followed by oxidation with TCNQ to give [Fc-CH=N-R] [TCNQ]2 salts. The electronic state of iron in these compounds are investigated by means of 57Fe Mossbauer spectroscopy.
