In this paper, we report the synthesis and photochromism of four aryl fulgides: (E)-1-(p-methoxyphenyl) ethylidene (isopropylidene) succinic anhydride (BF1), (E)-1-(p-methoxyphenyl) ethylidene (isobutylidene) succinic anhydride (BF2), (E)-α-naphthylethylidene (isopropylidene) succinic anhydride (NF1), (E)-β-naphthylethylidene (isopropylidene) succinic anhydride (NF2). Photochromic processes of these compounds have been studied by nanosecond laser flash photolysis technique, the reaction mechanism has been discussed. It was found that photoinduced cyclization of aryl fulgides is a fast process, and only the excited signlet state is involved in the photocyclization reaction.
