Materials

SiPcs are a class of metal phthalocyanine (MPc) that have attracted interest from our group and several others. Due to the oxidation state of the silicon, we observe two axial bonds that are perpendicular to the aromatic macrocycle. These axial bonds serve as chemical handles to impart solubility and tune surface and bulk properties without having a significant effect on the optical and electrochemical properties, a significant advantage over divalent MPcs such as copper phthalocyanine (CuPc) or zinc phthalocyanine (ZnPc). Interestingly, R2-SiPc derivatives appear to inherently behave as n-type semiconductors: they favour the transport of electrons over holes, which is uncommon for MPcs. Our group focuses on the synthesis, characterization and integration of this exciting class of materials into thin film electronics
