| 摘 要： | 1.2-二甲基-3-吲哚甲叉(异丙叉)丁二酸酐(1)(C_(18)H_(17)NO_3)与1.2-二甲基-3-吲哚乙叉(异丙叉)丁二酸酐(2)(C_(19)H_(19)NO_3)同属于吲哚俘精酸类化合物,它们的分子结构非常类似,只是(1)中为吲哚甲叉,(2)中为吲哚乙叉.但它们的光色性却差别很大.化合物(1)无光致变色性,化合物(2)则表现为良好的光致变色性.其原因在于结构的不同。

| Abstract: | The crystal structures of 1,2-dimethyl-3-indolylmethylidene succinic fulgide anhydride (1) and 1,2-dimethyl-3-indolylethylidene succinic fulgide anhydride(2)were determined by singe crystal X-ray diffraction analysis. The crystal data areC_(18)H_(17)NO_3(1), orthogonal space group Pbca, with a=10. 084(3)A, b=13. 966(4)A,c=20.945(6)A, V=2949. 8(15)A~3, Z=8; C_(19)H_(19)NO_3 (2), orthogonal space groupPbca, with a=7.988(3)A, b=25.782(10)A, c=15.664(5)A, V=3225.9(22)A~3,Z=8. R values are 0. 047 for(1) and 0. 059 for(2) respectively. The photochemical properties of (1) and (2) were reported. Compoud(1) is non-photochromic, compoud (2) changed from pale yellow to blue or green on irradiationat 365 nm or on exposure to indoor UV light either in crystal state or in solution(liquid or rigid plastic matrix). The differences in photochromic properties of compound (1) and (2) werediscussed. |
