Helicenes are molecules with ortho-fused aromatic rings that adopt an inherently chiral helical shape. This topology combined the extended π-conjugated system provides them excellent chiroptical and photophysical properties. These properties peculiarities make helicenes important candidates for conception of new switches. Several examples light-, redox- pH-triggered helicene-based switches have recently appeared in literature including from our group. Some multi-input and/or multi-output systems which changes can be triggered by different stimuli read-out techniques, attractive advantage functional materials.
