Abstract: The photochromism of salicylaldehyde-derived Schiff bases were studied from a view-point of structure-property relationship. It was found that the π-conjugated system and the flexibility of the molecular skeleton play an important role in the determination of the photochromic behavior. The molecules with smaller π-conjugated systems or flexible skeletons are easy to undergo the photochromism.

Key words: Salicylaldehyde-derived Schiff base, Photochromism, Time-dependent spectroscopy, Fluorescence spectroscopy, UV-Vis spectroscopy
