||Recently, a new group of organic semiconducting materials, conjugated polymers have attracted a good deal of attention as functional materials for organic materials, optoelectronic materials, biochemical detection due to their inherent properties. Because conjugated polymer fluorescence sensitive change by external stimulus, fluorescence chemical sensors with conjugated polymers are vital interest for the detection of chemical warfare compounds such as nerve agents. These days many researches have been studied to chemical or biological sensor for sensing nerve agent, toxic substance or small biomolecule. To achieve the purpose, we synthesis functional polyquinoxaline using 5,8-dibromoquinoxaline and 5,8-dibromo-2,3-diphenylquinoxaline. The materials obtained by electrospining with polyquinoxaline and PMMA (Poly(methyl methacrylate)). Because Sheet fabric by electrospining have wide surface area and flexible, can be applied to a variety to materials.
