Abstract:
We report polymer-guided assembly of chiral gold nanorods (AuNRs) in end-to-end (EE) and side-by-side (SS) modes, modulating their chiroptical responses. EE assemblies amplify circular dichroism (CD) response due to the interparticle plasmonic coupling along the continuously helical patterns of c-AuNRs along the chain direction, while SS assemblies reduce CD response as a result of racemic twisting.
