Helical nano-fibers of an optical active phthalocyaninato zinc complex: Chiral information transfer, I–V properties and nonlinear optical properties

• (S)-ZnPc (1) was self-assembled to helical supramolecular structures.
• The self-assemble behavior was systemically investigated.
• Nonlinear optical property of 1 was studied.
• I–V properties of the helical nanostructures formed from compound 1 were studied.

An optically active phthalocyaninato zinc complex containing eight chiral diethyleneglycol mono-(S)-2-methylbutyl ether moieties at the β-position of the phthalocyanine ring, namely (S)-ZnPc (1), was designed, synthesized, and characterized. Using a phase transfer method, the complex 1 was self-assembled to helical nanostructures and the self-assemble behavior was systemically investigated by electronic absorption and circular dichroism spectra, transmission electron microscopy and scanning electron microscopy. In addition, nonlinear optical (NLO) properties of complex 1 and I–V properties of the helical nanostructures formed from complex 1 were also measured.
