“…It has high symmetry, almost fully planar, and having electron delocalization over the molecule 1 . The development of nanoscience and nanotechnology allowed researchers to prepare nano‐sized phthalocyanines with unique features and promising applications, some of which are photovoltaic cells,, 2–4 chemical sensors, 5 LEDs, 6 OFETs, 7,8 microelectronic devices, 9 and photocatalysts 10–13 . Since they absorb light intensely within the solar spectrum, photocatalytic applications of phthalocyanines (MPcs) have been very popular 14–15 .…”

A novel photocatalyst, nano-sized zinc and cobalt phthalocyanines (MPc), are anchored on polyacrylonitrile (PAN) nanofibers in the presence or absence of TiO 2 and the process was realized with an innovative solution blow spinning (SBS) method for the first time. Novel nanofiber composites were characterized by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy techniques. According to the SEM micrographs, the immobilization of nano-Pcs on the surface of PAN nanofibers was uniform and does not involve agglomeration. The MPc/PAN composite yielded nearly complete degradation of methylene blue (MB) of a highly photocatalytic nature. It was also found that the presence of TiO 2 on MPc/PAN composite have no effect on photodegradation of MB. Also, the recycling of new photocatalysts required as little change as possible owing to their macroscopic structure and their flexible nature.

“…Sharma et al [7] reported earlier on the charge conduction process and photoelectrical properties of Schottky barrier device based on sulphonated nickel phthalocyanine. A MIS type Schottky barrier diode using lead phthalocyanine and copper hexadecachlorophthalocyanines thin film as interlayer were obtained and calculated the theoretical Schottky coefficient and the barrier height by Pakhomov et al [8]. Authours concluded in their work that rectifying behavior of device strongly depends on the conduction type in Pc layer.…”

The temperature dependent current-voltage characteristics of Ag/ZnPc/p-Si Schottky barrier (SB) diode are investigated in the temperature range of 300-450 K, and in the bias range of ± 1 V. By fitting the experimental data to space-charge limited conduction, bulk-limited Poole-Frenkel emission and thermo-ionic emission theory, it was observed that these models can not be applied to evaluate junction parameters for the investigated SB diode. Preliminary results indicated that the charge transport proceeds by different mechanism for low and high values of the applied voltage under forward and reverse bias conditions. It was found that the charge transport is governed by hopping processes for low values of the forward bias. However, for higher values of the forward bias, the charge transport controlled by the bulk limited procesess. The same voltage dependence was also observed for reverse bias conditions.
