The Preparation And Characterization Of The Fluorescent And Conductive Polyaniline Grafted With (8-Quinolinol Derivatives)

In Recent years, many research projects focus on development of Conducting polymer at home and abroad. Polyanilines(PAn) can be exploited in various appication ,because it has many unique propertyies, such as high electrical conductivity , electrochemical properties, environmental stability, optical and, cheap material,and so on.This paper mainly studys a new class of Conducting polymer—polyaniline derivative. Two monomers of Conducting polymer that 5-[(phenylamino)methyl]-8-Quin-olinol and 5-[(2-aminophenoxy)methyl]-8-Quinolinol were synthesized by material aniline, 2-nitrophenol, ordinary function material namely 8-Quinolinol etc.Conducting polymer of poly N-[5-(8- Quinolinol)ylmethyl]aniline (PNQMAn) and poly 2-[5-(8-Quinolinol) methoxy]aniline(PQMOAn) were synthesized by oxidating 5-[(phenylamino)methyl]-8-Quinolinol and 5-[(2-aminophenoxy)methyl]-8-Quinolinol with oxidant of (NH4)2S2O8 or HClO4. The doping PNQMAn and PQMOAn were prepared by doped with HCl, The production of each reaction was characterized by IR, UV—Vis Spectra. The fluorescent spectra of each complex of base and doping Conducting Polymer coordinated with Al3+,Zn2+ in solution was studied. The base and doping PNQMAn was characterized by X-ray diffraction. At last the conductibility of base and doping conducting polymer was mensurated The researchful result shows that the new conducting polymer ,whether doping or not, all have better fluorescence and conductivity at the same time, and the complexes have better fluorescence coordinated with Al3+,Zn2+ in solution.
