Supramolecular nano-twists/-helices formed from chiral or achiral molecules have considerable attraction due to formation/amplification of chirality during dynamic self-assembly. Recently, supramolecular chirality of organic molecules can get benefit through hybridization with metal nanoparticles due to its capability of optoelectronic applications. In particular, gold nanoparticles (Au NPs) have unique plasmonic properties which can be introduced by precise control of size and shape of AuNPs. Although the helical nanostructures with regular dimension and pitches are excellent templates for NP assembly, it is still challenging due to the lack of competitive molecular self-assembly scaffolds and NPs. Herein, we report the useful strategy for controlling the NP location within the peptide helical nanostructures using the enantiomeric molecular assembly. The regulated NP results in the distinguishable chiral plasmonic effect in response to circularly polarizing light. |
