Graphical Abstract

Thumbnail image of graphical abstract

A facile technique is reported to prepare globally aligned arrays of self-assembled peptide nanostructures within macroscopic hydrogels starting from a solution of peptide molecules with embedded π-conjugated oligomers. The alignment of the π-stacked conduits within these macrostructures is verified with polarized optical microscopy and leads to anisotropic photophysical and electrical properties.
