Abstract

AbstractPoly(peptide)‐wrapped unsubstituted metalophthalocyanines (Mt‐Pc's, Mt = Fe, Co) were synthesized by polycondensation of amphiphilic bifunctional active esters of amino acids (1 and 2), which form micellar or reversed micellar aggregates and solubilize Mt‐Pc's. Though Mt‐Pc's are insoluble in most organic solvents, the obtained poly(peptide)‐wrapped Mt‐Pc's are soluble in protic solvents such as formic acid, dichloroacetic acid, and trifluoroacetic acid. The wrapped Mt‐Pc's are stable, and their leakage out of the poly(peptide)s is not observed. UV‐Vis spectra revealed that the wrapped Fe‐Pc is predominantly in the monomeric state. ESR spectra confirmed the poly(peptide)‐wrapped structure of Mt‐Pc's.
