What happened

Supramolecular nanofibers paired with nanohole substrate improve exciton transport in organic solid Robert Egan Senior Editor Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new…

Why it matters

Coupling these nanofibers with a plasmonic gold nanohole substrate further doubles exciton diffusivity.

Common ground

By mitigating the limited diffusivity of singlet excitons in organic semiconductors, this approach offers a new strategy for improving optoelectronic technologies.
