Synthesis,Characterization,Properties Of A Novel Organic Magictic Materials Derived From Ferrocene

Ferrocene compouds are one of the most important family of organic compounds,which have an extensive range of application in magnetic materials,medicine,biology,nonlinear optical materials,electrochemical or photosensitive materials and fuel additives.Thus,it is of great significance to synthetize new type ferrocene compounds with specific properties in the field of materical and medical.This paper was made up of three chapters.In the first chapter,we summarized the application of ferrocene and its derivatives,coumarin compounds,organic materials and N-bromosuccinimide.In the second chapter,we have studied and synthesized a series of new coordination compounds derived from ferrocene and N-bromosuccinimide.These new coordination compounds were determined by X-ray photoelectron spectrum(XPS)and infrared spectroscopy(IR),and the mechanism was explored.Results showed that ferrocene was used as electron donor and N-bromosuccinimide was electron acceptor,they were connected with the Fe-O bond,and coordinated in two ways.The infrared spectroscopy test results show in ferrocene the compound connected with electron donating compared to the compounds conected with electron-withdrawing was more prone to coordination,higher yield.Magnetic property on ferrocene and N-bromosuccinimide complex was tested by MPMS.These results showed that ferrocene and N-bromosuccinimide complex are a kind of organic magnetic material,which has a low magnetic loss.It shows paramagnetic property at room temperature and shows antiferromagnetic property at temperatures below 14.5K.In addition,N-bromosuccinimide can be used as a coordinated reagent with the ferrocene is our innovation.The third part of the paper has been developed for the synthesis of six new ferrocene coumarin fluorescent magnetic materials containing,we tested their fluorescence properties,the results showed that the coordination compound fluorescent compounds has been significantly enhanced after addedN-bromosuccinimide and compounded.The main reason is that the addition of N-bromosuccinimide increases the conjugation degree of the molecule,thus enhancing the fluorescence properties of the material.
