摘要
环三磷***是由氮、磷原子交替排列形成一种定域型刚性六元环。这一结构特点与苯环相类似,该六元环环内的氮-磷键键长相等,可以将这些氮-磷键近似看做是在同一个平面上,环上磷原子可以被不同的取代基取代,取代基团在环平面的上下方均匀的分布着。环三磷***衍生物具有很好的生物学和化学性能,并且具有非常特殊的结构及取向结晶性能,是一种用来研究聚合物结构与性能间关系的优异模型。
本论文以甘氨酸钠盐和对羟基苯甲醛为原料,合成了对羟基苯甲醛甘氨酸钠希夫碱。进一步与六***环三磷***进行缩合反应合成了三个环三磷***对羟基苯甲醛甘氨酸钠衍生物。产物经纯化干燥后,利用红外光谱、1H核磁和13C核磁光谱等进行了结构表征,证明所得产物为目标化合物。运用紫外光谱法研究了环三磷***衍生物对磷酸吡哆醛和铜离子的识别功能,结果表明衍生物对二者均具有良好的识别能力。

Study on cyclotriphosphazene salicylaldehyde glycine ethyl and recognition of transition metal ions
Abstract
The cyclotriphosphazene is the cyclic phosphazene derivatives, polyphosphazenes series is a special intermediate. It is replaced by nitrogen, phosphorus atoms which are alternately arranged and it forms a given domain rigid six-membered ring. This structure is similar with a benzene ring. The nitrogen-phosphorus bond in the six-membered ring is same. The nitrogen - phosphorus bond can be seen in the same plane, and the phosphorus atom can be substituted by different substituents, the substituent group is uniformly distributed in the plane of the ring or on the bottom. Cyclotriphosphazene derivatives have good chemical and biological properties, and also have very special structures. Its orientation of crystalline properties is excellent model used to study the relationship between the polymer structure and properties.
The design is that the hydroxybenzaldehyde glycine sodium is based on the sodium salt of glycine and p-hydroxybenzaldehyde synthesized Schiff. Secondary the cyclotriphosphazene glycine sodium p-hydroxybenzaldehyde was synthesesed.
After the extract after drying, these products were obtained by the experiment. They were analysed by the infrared spectroscopy, 1H NMR and 13C NMR spectroscopy and proved the experimental structure of the product. The use of UV spectroscopy method the cyclotriphosphazene derivatives of metal ions recogniti
