Chiral photosensitive molecular switch, cholesteric liquid crystal composition, display panel and preparation method thereof

Abstract

Provided are a chiral photosensitive molecular switch, a cholesteric liquid crystal composition, a display panel, and a preparation method thereof. The chiral photosensitive molecular switch has two stable states, and may switch, in response to light irradiation, from one stable state to the other stable state which may stably exist. The cholesteric liquid crystal composition includes: a chiral photosensitive molecular switch, a bent-core molecular mixture, a rod-like single crystal mixture and a non-photosensitive chiral dopant. The cholesteric liquid crystal composition may be used to prepare a cholesteric liquid crystal display panel, where the cholesteric liquid crystal has two stable states with different handedness and may reflect light of different handedness.
