Fuel-driven
dissipative self-assemblies play essential roles in
living systems, contributing both to their complex, dynamic structures
and emergent functions. Several dissipative supramolecular materials
have been created using chemicals or light as fuel. However, electrical
energy, one of the most common energy sources, has remained unexplored
for such purposes. Here, we demonstrate a new platform for creating
active supramolecular materials using electrically fueled dissipative
self-assembly. Through an electrochemical redox reaction network,
a transient and highly active supramolecular assembly is achieved
with rapid kinetics, directionality, and precise spatiotemporal control.
As electronic signals are the default information carriers in modern
technology, the described approach offers a potential opportunity
to integrate active materials into electronic devices for bioelectronic
applications.
