通过两步Stobbe缩合反应合成了一种双杂环俘精酸研化合物,E,E-3,4-二[1-(5,5-二甲基-3-呋喃基)乙叉]-3,4-二氢呋喃-2,5-二酮(双呋喃俘精酸酐)。通过X射线单晶衍射,对目标产物的分子结构进行了研究,结果表明在该化合物中,2个反应中心的距离分别是0.3394和0.3406um,有利于光环合反应。研究了该化合物在不同溶剂中的光致变色性行为,并对目标产物在平行图象光信息存储中的应用进行了探索。
A two-ring fulgidate compound was synthesized by a two-step Stobbe condensation reaction. E, E-3,4-bis [1- (5,5-dimethyl-3-furyl) , 4-dihydrofuran-2,5-dione (bisfuran fulgide). By X-ray single crystal diffraction, the molecular structure of the target product was studied. The results showed that the distance between the two reaction centers was 0.3394 and 0.3406um, respectively, which was in favor of the photocyclylation reaction. The photochromic behavior of the compound in different solvents was studied, and the application of the target product in parallel image optical information storage was explored.
