合成了五个新的3-乙酰基吡咯衍生物,以它们为原料,进一步合成了五个新的吡咯取代的俘精酸酐。研究了五个俘精酸酐化合物在不同溶剂中的光致变色性能,考察了溶剂极性对俘精酸酐及其光致变色反应产物(7,7a-二氢吲哚衍生物)吸收光谱的影响,结果表明,随溶剂极性的增加吸收光谱发生红移。对7,7a-二氢吲哚衍生物的影响远比对俘精酸酐本身的影响显著的多。

Five new 3-Acetyl pyrrole derivatives and five new corresponding pyrryl substituted fulgides: E-(α )-(3-substituted pyrryl) ethylidene (isopropylidene) succinic anhydrides (3a～e) were synthesized. The photochromic properties of all synthesized fulgides in various solvents were studied. The solvent effects on the absorption spectra of fulgides and their coloured forms (7, 7a- dihydroindole derivatives) were also investigated. It was found that the absorption maxmium of the 7, 7a-dihydroindole derivative exhibites much stronger bathchromic shift than that of fulgide with the increasing of the polarity of the solvents.

Key words: PHOTOCHROMISM, PYRROLE, SOLVENT EFFECT, ABSORPTION SPECTROMETRY, HETEROCYCLIC COMPOUNDS
