Synthesis of Hafnium and Zirconium Phthalocyanine
What I have done during my internship in Professor Drain’s lab is the synthesis of zirconium and hafnium phthalocyanine dichloride by building a phthalocyanine ring around the metal ion (using Zr/Hf tetrachloride as starting material). The zirconium and hafnium dichloride phthalocyanines were prepared via direct interaction between 1,2-dicyanobenzene and zirconium and hafnium tetrachloride. The structure that was obtained was studied by a UV VIS spectrometer dissolved in DMSO solutions and NMR. These two compounds are similar; both were only soluble in DMSO. In order to make these compounds more soluble in other organic solvents that do not contain oxygen we made hafnium and zirconium-diacetate phthalocyanine from the zirconium and hafnium dichloride phthalocyanines. The purpose for this synthesis is to use them in solar cell devices and this requires the metallophthalocyanines to bind to the TiO2 surface.
