| Research Abstract |
In this study, we demonstrated an acetalization reaction as a versatile method to immobilize aromatic aldehyde molecules on surfaces of metal oxide semiconductor such as indium tin oxide. A terephthalaldehyde(TPA) immobilized on the ITO surface readily react with aromatic diamines to form azomethine oligomers with controlled molecular length. We have successfully developed a simple method to produce electrospun fibers of conjugated polymers with controlling their number and diameter. We observed large optical anisotropy and enhancement of electrical conductivity as increasing molecular orientation by mechanical stretching of nanofiber.
