酚性化合物

The heliotrope new shoots contain more polyphenal,catechin,flanone and more L-EGCG which is healthful to human beings than the pure green new shoots.

安化群体品种茶树上的红紫色芽叶较纯绿色芽叶含有较多的茶多酚、儿茶素和黄酮类化合物，保健性强的L-EGCG含量亦偏高。

From optical BINOL, the chiral phosphoryl azide compound was prepared. Its application as chiral auxiliaries in the stereoselective ring-opening of meso-epoxides was examined. No obvious asymmetric induction, however, was observed.

从光学活性的联二萘酚出发合成得到了手性磷叠氮化合物，并将其应用于环氧化合物的不对称开环反应中，考察了它作为手性辅助剂在该反应中的不对称诱导效果。

Since the molecular clip of glycoluril is also an important supramolecular host but few studies have been done in the field of fluorescent chemosensor,we proceeded with some experiments and research in this field as a trial and designed a series of novel fluorescent chemsensors including different three-dimensional cavities by introducing the fluorophores into the receptor.Their recognition and sensing abilities toward various metal ions and neutral guests were studied.

因此，我们(来源：A1dBC论文网www.abclunwen.com)做了一些尝试性的研究，在传统的甘脲主体化合物上引入荧光发色团，设计了一系列新型的、拥有不同立体空腔的荧光分子夹，并研究了它们对各种金属阳离子以及酚类中性客体分子的识别和荧光传感性能。
