The first representatives of thiophene derivatives with two fulgimide fragments in one molecule have been obtained by the condensation of (3Z)-3-[1-(2,5-dimethyl-3-thienyl)ethylidene]-4-isopropylidene-2,5-furandione with aromatic diamines. The photochromic properties of the obtained compounds have been investigated and the effect of a spacer, linking the two fulgimide fragments, on the reaction rates
通过(3Z)-3- [1-(2-(2,5-二甲基-3-噻吩基)亚乙基] -4-异亚丙基-2,5的缩合反应获得在一个分子中具有两个fulgimide片段的噻吩衍生物的首个代表-呋喃二酮与芳香族二胺。已经研究了获得的化合物的光致变色性质,并且研究了连接两个富马来酰亚胺片段的间隔基对这些化合物的光致变色和光致脱色反应速率的影响。
