Direct Conversion of Light into Continuous Mechanical Energy by Photoreversible Self-Assembly: A Prototype of a Light-Powered Engine

En route to a clean engine: The concentration of a chemical system containing an azobenzene derivative can be varied cyclically by light, and this variation has been exploited to produce continuous work. The cyclic concentration change of the system is the result of a light‐controlled self‐assembly/...

Description
Summary:En route to a clean engine: The concentration of a chemical system containing an azobenzene derivative can be varied cyclically by light, and this variation has been exploited to produce continuous work. The cyclic concentration change of the system is the result of a light‐controlled self‐assembly/disassembly process.
