Front Cover: Reversible Broad‐Spectrum Control of Selective Reflections of Chiral Nematic Phases by Closed‐/Open‐Type Axially Chiral Azo Dopants (ChemistryOpen 6/2017)

The Front Cover demonstrate the photocontrol of selective reflection colors that originate from the self‐organized helical structure of chiral nematic liquid crystals (N*LCs) by using closed‐/open‐type dopants. The drastic structure changes of the dopants by light stimuli enable reversible broad‐spectrum control of selective reflections of N*LCs with opposite helical sign. In their Full Paper, H. Nishikawa et al. focus on reversible broad‐spectrum control of selective reflections of opposite‐handed chiral nematics by using new chiral dopants. More information can be found in the Full Paper by H. Nishikawa et al. on page 710 in Issue 6, 2017 (DOI: 10.1002/open.201700121).[Image: see text]
