Titanium-based tetrakis-2,3-[5,6-di(substituted)pyrazino]porphyrazine. Synthesis and characterization

Tetrapyrazinoporphyrazine (TPysPz) ligands and metal complexes find, generally, application as electronic materials and catalysts. Considering the limited application of Titanium (Ti), we prepared and characterized a family of ligands and Ti‐based complexes of tetrakis‐2,3‐[5,6‐di‐R8‐pyrazino]porphyrazine (R = H, 2‐Py, Ph). UV/Vis measurements in different solvents confirm molecular aggregation, which results more pronounced in the presence of 2‐pyridil and phenyl substituents on the macrocycle edge. Because of low solubility, solid state NMR was applied for structure characterization.
