Case Studies
Synthesis of functionalized zinc phthalocyanines as hole transporting materials for organic electronics
This study describes the synthesis and characterization of two zinc phthalocyanines functionalized with benzothienobenzothiophene derivatives as new potential p-type semiconductors for electronic and optoelectronic technologies. When implemented in perovskite solar cells, both the molecules showed an interesting hole transport activity even in absence of chemical doping.

Preparation of thin films of (FePc)2C obtained by spin coating or Langmuir Blodgett for sensing applications and studies on their interaction with NO2
Nitrogen oxides are among the environmental pollutants to be kept strongly under control and metallophthalocyanines (Pc) have proven over the years to be particularly suitable for their detection when implemented in opportune sensors. The study of μ-carbide bridged iron phthalocyanine films deposited by spin coating and Langmuir-Blodgett allowed to compare their behavior in the presence of NO2 in terms of gas-molecule chemical interaction and variation in the electrical conductivity of the films. The similarities and differences between the two systems have been rationalized taking into account the different structural and morphological characteristics of the films induced by the two deposition techniques.
