环三磷腈的单链侧基衍生化及其性质

以制得的4种原儿茶醛舭氨基酸钠缩合产物与六氯环三磷腈为基本原料，同位单链侧基衍生化后，其他氯原子分别以对氨基苯酚封闭，合成4种环三磷腈α-氨基酸钠支化衍生物。利用IR、^1H NMR、^13C NMR分析方法对产物进行了结构表征，证实为目标化合物。通过紫外-可见光谱、电化学工作站等实验方法，考察了衍生物对金属Cu^2＋离子的识别性能及电化学性质。结果表明：环三磷腈α-氨基酸钠支化衍生物对Cu^2＋离子的选择性识别作用明显，且呈明显的剂-效关系。Fe（CN）6^3-/4-电对在支化衍生物修饰玻碳电极表面的电化学反应过程为扩散控制。并随着衍生物修饰剂量的增大和扫描速率的增加氧化还原峰电流逐渐增强，对Fe（CN）6^3-/44电对的电极反应表现出电催化作用（本刊编者注：本文中Fe（CN）6的右上角应为3-/4-）.

Derivatization and Properties of Cyclotriphosphazene Derivatives of Mono-Pendant Group

Four cyclotriphosphazene α-amino acid sodium branched derivatives were synthesized with four compounds which had obtained by protocatechualdehyde and α-amino acid sodium and hexachlorocyclotriphosphazene as the basic raw material. After the parity single side group derivatization, other chlorine atoms closed by p-aminophenol. Their structures were characterized by means of IR, ^1H NMR, and ^13C NMR, all the spectral data showed that these derivatives confirmed as our target products. Besides, the recognition properties of these cyclotriphosphazene derivatives with different metal ions and electrochemical property had been studied by the methods of UV-vis and electrochemical workstation respectively. The results indicated that these branched derivatives have obvious selective recognition function with Cu^2＋, and present dose-effect relationship obviously. The electrochemical reaction process of Fe（CN）6^3-/4- on the surface of branched derivatives modified glassy carbon electrode is diffusion controlled, and the redox peak current increased gradually with the addition of these derivatives modified does and scanning rate, the modified electrodes have ele.ctrical catalysis effect on Fe（CN）6^3-/4-.
