Abstract: The bidirectional interconversion between ketone and enol structures of 4-cyclopentene-1,3-dione derivatives was realized by photoswitching of fused dithienylethene using UV and visible light. A loss of antiaromaticity offered the driving force for light-triggered enolization and… read more here.
