Synthesis And Properties Of A New Water-soluble N-substituted Carboxyl Modified Aromatic Amine Conducting Polymer

Conductive polymers as an important branch of the organic material, due to their goodreversible redox behavior and physical and chemical properties of both metal and plastic, theyhas exhibited wide application potential in biological sensors, artificial muscle, electronicshielding device, display device, electrochemical energy storage device, corrosion inhibitor,etc. At present, because of the characteristics of insoluble and infusible, their developmentsare impeded seriously, and therefore to obtain a soluble and high electric conductive polymerhas an extremely vital significance. And water as a good solvent, is environmental friendly,low-cost and recyclable, etc. if we can develop a kind of water soluble conductive polymers,which will bring a new breakthrough to the development of conductive polymers certainly.This study adopt the method of N-substituted carboxyl modified the conductivepolymer to obtain a soluble and excellent processing properties’ derivative of polyaniline andpolydiaminonaphthalene. Take advantage of the amino and imino in the molecular chain ofpolydiaminonaphthalene can efficient complex with metal ions, using the metal Eu(Ⅲ) ionsof rare earth doping polymer to prepare an excellent light emitting performance of thephotoelectric material. The main contents are as follows:1. The N-phenylglycine was polymerized by chemical oxidation polymerization andelectrochemical polymerization. Its structure was characterized by Infrared spectroscopy(FT-IR), UV-visible spectroscopy (UV-vis), nuclear magnetic resonance (NMR) andelemental analysis. Its polymer aggregation structure was characterized by XRD. Finally, itsproperties of dissolution and conductive and electrochemical reversibility arecomprehensively compared with the polyaniline.2. A novel derivative of1,8-diaminonaphthalene (1,8-NDAN) was synthesized bychloroacetic acid and1,8-diaminonaphthalene (1,8-DAN). Its structure was characterized byFT-IR and NMR technology. According to the synthesis conditions and reaction phenomenon,the mechanism of synthesis reaction was proposed. Then, the monomer of derivative waspolymerized by chemical oxidation polymerization, and its structure and properties werecharacterized.3. Poly1,8-diaminonaphthalene (P18DAN) and its derivative modified by N-substitutedcarboxyl (P18NDAN) were doped with Eu(Ⅲ) ions. Their fluorescence properties and itsrelationship with the content of Eu(Ⅲ) ions were discussed.
