of a ferroelectric SmC* liquidcrystal based on a photoinduced sign inversion of the spontaneouspolarization (PS) induced by a single chiraldopant. This is achieved without concomitant destabilization of the SmC* phase using the "ambidextrous" dopant 6-((R,R)-2,3-difluorooct-1-yloxy)-5'-nitro-6'-((R)-2-octyloxy)thioindigo. The (R)-2-octyloxy side chain is sterically coupled to the thioindigo core
