摘要： 近年来,在光致变色材料研究领域中,人们的注意力从无机材料转移到有机材料。O-杂环俘精酸酐衍生物就是其中一类,但N-杂环俘精酸酐还没有引起人们注意。N-杂环俘精酸酐也能象O-杂环俘精酸酐一样在紫外光照射下环合成双氢吲哚的衍生物,N的给电子能力比O强,因此其双氢吲哚衍生物的吸收波长会出现红移。

Abstract: The title compound has been synthesized and the crystal structure has been determined by single-crystal X-ray diffraction techniques. Mt=259, triclinic crystal, space group P1 with a=8.116(1)Å,6=8.903(2)Å, c=9.995(2)Å, a=86.96(1)°, β=74.27(1)°, V=74.35(1)°, V=669.1(2)Å3and Z=2. The structure was solved by direct methods and Fourier Synthesis and refined by block-matrix least square method. The final result gives R=0.060 for 1196 independent reflections with |F|/σ(|F|)≥2.5. The compound is a (Z)-coplane molecule.
