ABSTRACT
In 1907, Braun and Tcheriac discovered phthalocyanine materials. Initially, phthalocyanine materials were mainly used as dyes and pigments (Liping Ma et al. 2004, Michael C. Hamilton et al. 2004), and now phthalocyanine materials are widely used in printing ink, paint, rubber, plastics, textile, leather and food. At present, phthalocyanine organic semiconductor material is one of the most active research directions in the field of photoelectric materials, and it has received widespread attention because of its optical, electric and magnetic characteristics. Further study shows that the material of phthalocyanine is a kind of nitrogen containing macrocyclic compounds (Florian Eder et al. 2004). The electron distribution of phthalocyanine is very uniform, so it has very good stability. Meanwhile, the hole of the phthalocyanine ring can accommodate cobalt, iron, copper, nickel, zinc and many other metals to form phthalocyanine metal compound (B. Bialek. 2003). Its molecular structure is shown in Figure 1.
