Dissipative and Autonomous Square-Wave Self-Oscillation of a Macroscopic Hybrid Self-Assembly under Continuous Light Irradiation
Abstract
Building a bottom-up supramolecular system to perform continuously autonomous motions will pave the way for the next generation of biomimetic mechanical systems.
In biological systems, hierarchical molecular synchronization underlies the generation of spatio-temporal patterns with dissipative structures.
However, it remains difficult to build such self-organized working objects via artificial techniques.
Herein, we show the first example of a square-wave limit-cycle self-oscillatory motion of a noncovalent assembly of oleic acid and an azobenzene derivative.
The assembly steadily flips under continuous blue-light irradiation.
Mechanical self-oscillation is established by successively alternating photoisomerization processes and multi-stable phase transitions.
These results offer a fundamental strategy for creating a supramolecular motor that works progressively under the operation of molecule-based machines.
