| Popis: | Cobalt phthalocyanine nanowires with new crystal structure and broad optical absorption spectra were fabricated by using organic vapor phase deposition method. The morphology, crystal structure and optical properties of CoPc nanowires were characterized by SEM, X-ray diffraction, Fourier transform infrared and UV-visible spectroscopies. Analyses of X-ray diffraction patterns and Fourier transform infrared spectra indicate that the crystal structure of CoPc nanowires represents a new polymorph, which is designated J-CoPc. These J-CoPc nanowires with high directionality (average diameter ∼50 nm) surprisingly possess much broader optical absorption spectra in the visible spectral region than those of the α- and β-phase CoPc, enabling high potential for practical applications in novel molecular electronic/optical devices. |
