Uniaxially Oriented Peptide Crystals for Active Optical Waveguiding

Riding the waves: An aldehyde triggers oriented long-range crystallization of self-assembling fibrous diphenylalanine peptide networks (see picture). The crystal growth is self-adjustable and likely subject to kinetic regulation, which leads to the 3D confinement of uniaxially oriented substructures in the resultant crystal. The peptide crystals exhibit remarkable thermal stability and optical waveguiding properties. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
