Abstract: This paper reports on synthesis, association in solution, and Langmuir-Blodgett monomolecular layer formation of Hz, Mg, Co, Ni, Cu, Zn, Pd, Pt, Bi, and Pb phthalocyanine compounds with cumylphenoxy peripheral substitution on each benm ring at either the 2-or 3-position (tetracumylphenoxy-substituted isomer mixture). The degree of association is dependent on the identity of the complexed ion and varies from monomeric for the Pb ...
