We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

Among the open-chain crown ethers and cryptands with a same structure, the compounds disubstituted at the amide nitrogen atoms show the larger extractability for Am and Eu than the monosubstituted ones. The compounds disubstituted at the amide nitrogen atoms by two phenyl groups show the larger extractability for Am and Eu than those by two alkyl groups.

为了研究侧链含有偶氮苯基的水溶性共聚物的光异构化对脂质体内包容物的光控释放的影响，设计合成了N－异丙基丙烯酰胺和丙烯酰胺基偶氮苯的共聚物。

The obtained potential energy curves disclosed that a four-state cycle existed in the ground and excited states. It was also found that the activation energy for the methyl transfer was higher compared to the phenyl transfer, which was consistent to the experimental results that the photoisomerization of the phenyl substituted derivative was more rapid than the methyl substituted derivatives.

对反应势能面的研究发现，在光异构化反应中化合物M21和M21、M31的基态和激发态虽然都可以构成四能级反应过程，但由于M21异构化过程的活化能较高，使其所构成的四能级反应难以进行，这就从理论上解释了迁移基团为甲基的M21变色性能低于迁移基团为苯基的M31的实验结果。

In comparison with 〓ligand the substitution of one phenyl groupby pyridyl ligand renders this cluster a self defocusing effect different with previousbutterfly shaped clusters, so the peripheral ligands may also play an important role onthe NLO effects.
