The good photochromic properties was the new target of heterocyclic fulgides development. The new compound, (E)-2-[1-(5-chloro-2-methylthiophen-3-yl)ethylidene]-3-isopropylidene succinic anhydride, was synthesized using 2-methyl- thiophene and diethyl succinate as the starting materials by steps of chlorination, acetylation and Stobbe condensations, and its structure was fully characterized by 1H NMR, 13C NMR and MS techniques. The photochromic properties of the target product were studied under the different illumination time.

Key words: fulgide, photochromism, Stobbe condensations
