Organic nanofiber of copper phthalocyanine

In this study, we successfully fabricate one-dimensional (1D) nanostructure of Copper Phthalocyanine (CuPc), whose bulk form are normally used as a blue pigment and a hole transfer layer for the organic light emitting diode. With the vacuum evaporation method, the morphology of CuPc deposited at room temperature exhibits smooth surface, while for growth at higher temperature, the film showed a tendency to island growth (dewetting). These CuPc nanofibers also possessed field emission characteristic, which provide an opportunity to evaluate the feasibility for organic molecular fibers to play a role as electron emitters.
