Studies On Branched Derivatized,Properties And Recognition Of Cyclotriphosphazene

The inorganic framework of cyclotriphosphazene is very stable,and because phosphorus-chlorine bond are very active,side groups can be introduced by simple substitution reaction,and can have a variety of substitution patterns.Regulating the structure of pendant groups,so that the cyclotriphosphazene and its derivatives have a wide range of integrated nature.Fifteen cyclotriphosphazene schiff base branched derivatives were synthesized with different compounds such as protocatechualdehyde??-amino acid?p-aminophenol?Anisidine and so on,and cyclotriphosphazene as the basic raw material.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 of cyclotriphosphazene?-amino acid sodium branched derivatives and cyclotriphosphazene anilines branched derivatives 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 Cu²⁺,and present dose-effect relationship obviously;The electrochemical reaction process on the surface of branedch derivatives modified glassy carbon electrode is diffusion controlled,and have a certain electrochemical action.Research contents of the thesis is not only to expand the derivation methods and species groups of cyclotriphosphazene compounds,and also reveals the change of cyclotriphosphazene side groups and the dependence of application area and value.Through a series of studies on cyclotriphosphazene branched derivatives can provide for further study of a reliable theoretical basis for identifying ion probes and molecular logic gates constructed to provide critical alternative materials,with unlimited follow-up development and research space.
