title: Fabrication and characteristics of organic semiconductor nanoparticles of copper phthalocyanine oligomers.
abstract: Nanoparticles of copper phthalocyanine oligomers (O-CuPc) with peripheral carboxylic acid groups have successfully been prepared by a simple method of liquid phase direct precipitation in the presence of different surfactants. X-ray diffraction patterns, transmission electron microscopy, and UV-visible spectra are employed to characterize the novel organic nanoparticles. The sizes and size distribution of the resulting O-CuPc nanoparticles show a noticeable dependence on surfactants. Nonionic surfactant is helpful in forming uniform nanoparticles. Also we observe a remarkable nanosize effect of the O-CuPc particles.
