In this study, nonionic surfactant sorbitan trioleate (Span 85) was modified with Cibacron Blue F-3GA to become an affinity surfactant (CB-Span 85) and to form affinity-based reversed micelles while dissolved in hexane. Since the CB molecule possesses a specific conformation that mimics nicotinamide adenine dinucleotide, it can bind strongly and specifically to a wide range of nucleotide-dependent enzymes such as dehydrogenases and kinases. Moreover, high protein transfer efficiency in the reverse micelles can be easily achieved by controlling the ionic strength of the aqueous phase.

本实验使用非离子型界面活性剂Span 85与蓝色染料分子Cibacron Blue F-3GA结合，形成具有亲和性的界面活性剂 CB-Span 85，由於CB染料分子具有与NAD+相似的结构，可与含核苷酸部位的蛋白质具有亲和力，将CB-Span 85溶於有机溶剂形成反微胞相，可有效的提高反微胞的选择率，可以只控制离子强度来调节蛋白质进出反微胞的效率。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.

三脚架配体所带的羧基是一个很好的桥联基团，配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来，构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现：(1)用配体的π-π〓跃迁波长进行激发，配合物均显示出稀土离子的特征发射峰，同时，配体的荧光峰没有出现，这说明在三脚架配体与稀土离子间进行了有效的能量传递。
