Abstract

A family of copper and zinc phthalocyanine-based amphiphililes possessing racemic and optically active diol units, (rac)-ZnPc(OH)₁₆, (rac)-CuPc(OH)₁₆, and (S)-CuPc(OH)₁₆, have been synthesized. The self-assembling properties of these amphiphiles in aqueous solution have been studied by UV-vis, Fourier transform infrared (FTIR) and circular dichroism (CD) spectroscopies, X-ray diffraction (XRD) patterns, and transmission electron microscopy (TEM). Only the copper complexes produced fibrous assemblies from aqueous solutions through two noncovalent bondings: π-π interaction among phthalocyonine rings and hydrogen bonds among diol units. The formation of fibrous assemblies strongly depends on the central metal of the phthalocyanine complex. The optically active (S)-CuPc(OH)₁₆ is stacked and arranged in a left-handed helix. The chirality of diol units in (S)-CuPc(OH)₁₆ also affects the intercolumnar lattice of phthalocyanine stacks.
