| Abstract: | Eleven new ferrocenyl Schiff bases containing a benzene ring and C?N in a conjugating chain have been synthesized by facile methods and characterized by 1H NMR, elemental analysis and fast atom bombardment mass spectrometry. Cyclic voltammetry was used to determine their electrochemical properties and electron‐withdrawing effects. It is shown that these pull–push ferrocenyl compounds have nonlinear optical responses according to their electronic absorption spectra and powder second harmonic generation measurements.
