合成了8个反 -1,2-双[2-(5-取代苯基恶唑基)]环丙烷和2个1,2-双[2-取代苯基恶唑基)]乙烷,其中9个为新化合物.讨论了化合物的结构与其电子光谱及荧光量子产率间的关系.发现恶唑环与三元环间存在一定程度的共轭,并解释了上述化合物荧光量子产率较低的现象.

Eight trans-1,2-bis[2-(5-substituted phenyloxazolyl)]cyclopropanes I (R = Ph, substituted Ph) and two of 1,2-bis[2-(5-substituted phenyloxazolyl)]ethanes II (R = Ph, 4-MeOC6H4) were synthesized. Nine of them are new compounds The relationships between the resp. structures of these compounds and their corresponding electronic spectra, fluoroescence quantum yields were discussed. The conjugations between cyclopropane ring and oxazole rings were found and the reason why these compounds have low fluorescence quantum yields was discussed.

Key words: CONJUGATION, ELECTRONIC SPECTROSCOPY, STRUCTURE AND PROPERTY CORRELATION, CYCLOPROPANE P, CYCLOPROPANE P, PHENYL GROUP
