Abstract

A new asymmetrical Nickel phthalocyanine was synthesized by increasing the temperature of the classical synthetic method, and characterized by MS, IR and UV-Vis spectroscopy. The nanotubes of NiPc2 were prepared in large scale by self-assembling via a simple solvent diffusion method. The size of them was 50-120 nm in diameter and 2-10μm in length. The nanostructure, disclosed by XRD and UV-Vis, was a kind of highly long-range ordered lamellar arrangement of molecules. UV-Vis spectra demonstrated that the nanostructure is a J-type aggregate because of the red shift of the Q-band of the nanotubes. And the formation mechanism of nanotube has been proposed..
