Manganese phthalocyanine(MnPc) nanostructures with different morphologies were prepared on porous anodic alumina oxide(AAO) at different substrate temperature(T_S=50 ℃,80 ℃,120 ℃,180 ℃,240 ℃) in an organic molecular beam deposition(OMBD) system.The nanostructures morphologies were studied using scanning electron microscopy(SEM) and the results showed that the nanostructures morphologies could be modulated by the control of T_S,as a result,the continuous film was obtained at 50 ℃,whereas the nanorods(NRs),nanoribbons(NBs),nanowires(NWs),nanosheets(NSs) and nanoparticles(NPs) were facilely generated as T_S increased.At the same time,the density and the uniformity of the nanostructures decreased.The results of X-ray diffraction(XRD) indicated that only the(3-phase polymorph formed throughout the growth process irrelevant to the T_S.Additionally,the ultraviolet visible(UV-Vis) absorption spectra demonstrated that the main absorption bands of MnPc nanostructures showed a remarkable band broadening as the T_S was increased.

These nanostructures morphologies were studied using scanning electron microscopy (SEM) and the results showed that the nanostructures morphologies could be modulated by the control of T_S, as a result, the continuous film was obtained at 50 ° C, while the nanorods (NRs) nanoribbons (NBs), nanowires (NWs), nanosheets (NSs) and nanoparticles (NPs) were facilely generated as T_S increased. At the same time, the density and the uniformity of the nanostructures were decreased. The results of X-ray diffraction ( XRD) indicated that only the (3-phase polymorph formed throughout the growth process irrelevant to the T_S.Additionally, the ultraviolet visible (UV-Vis) absorption spectra demonstrated that the main absorption bands of MnPc nanostructures showed a remarka ble band broadening as the T_S was increased.
