摘　　要：针对杂环俘精酸酐良好的光致变色性能,以2-甲基噻吩和丁二酸二乙酯为原料,经过氯代、乙酰化、Stobbe缩合等反应合成了(E)-2-[1-(5-氯-2-甲基噻吩-3-基)乙亚基]-3-异丙亚基丁二酸酐,其结构经1H NMR,13C NMR,MS表征确认;初步考察了在不同的光照时间下目标产物的光致变色性能.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-methylthiophene 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.
