Abstract

Upon UV irradiation of a bent-core liquid crystal (LC) bearing an azo linkage doped with chiral molecules, a photo-induced transition takes place from BPI to BPIII. BPIII is stabilised over 20 °C, while the widening of the BPI range is not so remarkable. The mechanism of photo-induced BPI–BPIII transition is also discussed.
