Photo‐patternable cholesteric materials that combine fluorescence and a photochemically variable helical pitch have been investigated. Two cholesteric mixtures containing chiral photochromic (see Figure) as well as fluorescent dopants are examined. It is shown that photoregulation of both the fluorescence intensity and the polarization state of the emitted light can be realized.
