Programming and Dynamic Control of the Circular Polarization of Luminescence from an Achiral Fluorescent Dye in a Liquid Crystal Host by Molecular Motors

Circular polarized light is utilized in communication and display technologies a major challenge to develop systems that can be switched between left right circular luminescence with high degrees of polarization enable multiple addressable stable states. Luminescent dyes Liquid Crystal (LC) cholesteric phases are attractive generate, amplify modulate circularly (CPL). In the present study, we employ light-driven molecular motors as photo-controlled chiral dopants LCs switch handedness LC from an achiral dye embedded mesogenic material. Tuning color CPL retention time photoprogrammed helicity demonstrated making use variety dyes. The flexibility offered by design based on inherently unidirectional rotary provides full control over non-invasively light, opening possibilities for pixilated displays externally polarization.
