摘要/Abstract

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 2a~2c including different aromatic ring systems were synthesized from nopinone which was the derivative of renewable natural β-pinene. In the solid state, compounds 2a~2c exhibit different fluorescent colors. Compounds 2b and 2c showed the positive solvatochromism phenomenon, and they have different fluorescence colors in different polar solvents. In addition, compounds 2b and 2c have significant aggregation-induced emission (AIE) effect. Compounds 2b and 2c 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 2b and 2c have good application prospects as organic solid luminescent materials.
Key words: nopinone, β-diketonate, aggregation-induced emission (AIE) effect, solvatochromism
