What contributes to the choice of a metal in pthalocynanines?What properties give assurance of a good choice? and why is Zinc often preffered than other metals ?e.g. Aluminium, Copper, Indium etc
Although I am not chemical engineering specialist but based on the work on the corrosion and corrosion green inhibitors I got better for aluminum and its alloys which have good phthalocyanines structure with the green tea and tulsi extract Molecular geometry. You may check bellow

The choice of metal in the synthesis of metallophthalocyanines depends on several factors, including the desired properties and intended applications of the resulting compound. Metallophthalocyanines are a class of coordination compounds consisting of a central metal atom surrounded by phthalocyanine ligands.
The selection of the metal ion can influence the electronic, optical, magnetic, and catalytic properties of the metallophthalocyanine. Different metal ions can have varying effects on the absorption and emission spectra, redox properties, stability, and reactivity of the compound.
Commonly used metal ions in metallophthalocyanine synthesis include:
Copper (Cu): Copper phthalocyanine (CuPc) is one of the most extensively studied metallophthalocyanines due to its interesting electronic properties, including its semiconducting behavior. It is often used in organic electronic devices such as organic field-effect transistors (OFETs), solar cells, and sensors.
Zinc (Zn): Zinc phthalocyanine (ZnPc) is another widely used metallophthalocyanine. It exhibits good stability and has applications in organic semiconductors, photovoltaics, and organic light-emitting diodes (OLEDs).
Nickel (Ni): Nickel phthalocyanine (NiPc) is known for its magnetic properties. It finds applications in magneto-optical devices, data storage, and spintronics.
Cobalt (Co): Cobalt phthalocyanine (CoPc) is a paramagnetic metallophthalocyanine. It is used in various applications such as gas sensors, catalysts, and electrochemical devices.
Iron (Fe): Iron phthalocyanine (FePc) is another metallophthalocyanine with interesting magnetic properties. It is used in magneto-optical devices, data storage, and spintronics.
These are just a few examples, and there are other metal ions used in metallophthalocyanine synthesis, such as manganese (Mn), chromium (Cr), and platinum (Pt), depending on the desired properties and applications. The choice of metal also depends on factors like cost, availability, and compatibility with the desired synthesis conditions.
