摘　　要：以天然可再生资源β-蒎烯衍生物诺蒎酮为原料,合成了3个含有不同芳环体系的诺蒎烷基β-二酮氟化硼络合物2a^2c.在固体状态时,化合物2a^2c呈现不同的荧光颜色.化合物2b和2c具有显著的溶剂化显色效应,在不同极性溶剂中荧光颜色发生显著变化.此外,化合物2b和2c具有显著的聚集诱导发光(AIE)效应.将化合物2b和2c制作成电致发光器件I和II,器件I发出绿色光,而器件II发出黄色光.结果说明化合物2b和2c作为有机固体发光材料具有良好的应用前景.Three difluoroboron(BF2)β-diketonates 2 a^2 c including different aromatic ring systems were synthesized from nopinone which was the derivative of renewable naturalβ-pinene.In the solid state,compounds 2 a^2 c exhibit different fluorescent colors.Compounds 2 b and 2 c showed the positive solvatochromism phenomenon,and they have different fluorescence colors in different polar solvents.In addition,compounds 2 b and 2 c have significant aggregation-induced emission(AIE)effect.Compounds 2 b and 2 c were made into electroluminescent devices I and II,and device I and II emit green light and yellow light,respectively.The results indicate that compounds 2 b and 2 c have good application prospects as organic solid luminescent materials.
