The new tetra substituted metallophthalocyanines bearing four Schiff bases on periphery: Synthesis, spectroscopic properties and investigation of the effect of various central metals on aggregation properties

In the present study, new Schiff base compound (Z)-4-((quinolin-2-ylmethyleneamino)methyl)phenol (3), its phthalonitrile derivative (Z)-4-(4-((quinolin-2-ylmethyleneamino)methyl)phenoxy)phthalonitrile (4) were synthesized in the first step. Then, zinc(II) (Pc‒5), cobalt(II) (Pc‒6) and copper(II) (Pc‒7) phthalocyanines containing Schiff base group with quinolin moiety on peripheral positions were synthesized. All new compounds were characterized by general spectroscopic techniques. Aggregation properties of the obtained metallophthalocyanines were researched in polar and apolar solvents.
