“…When a photoresponsive dopant was used with a lightinsensitive dopant with opposite handedness, by adjusting the molar ratio of these two dopants, the sign of the overall HTP can be switched by varying the HTP of photoresponsive dopants, that is, the handedness of this system can be inverted by light. This strategy of using multiple dopants to obtain the cholesteric phase was demonstrated by several groups [82][83][84]. In 2001, Kurihara et al reported a photo-controlled handedness switching of the photoresponsive CLCs consisting of chiral azobenzene (S)-11 and non-photoresponsive (R)-26 [82] (Fig.…”

“…Recently, Gvozdovskyy et al. used this dopant in combination with the photo‐insensitive dopant R811 and observed light‐driven handedness inversion of the induced CLC fabricated from the nematic liquid crystal MLC6884 (Merck) . The observed helicity inversion is due to the interplay of the opposite HTP signs of the two chiral dopants in the nematic host.…”

“…Kürzlich verwendeten Gvozdovskyy et al. diesen Dotanden in Kombination mit dem lichtinsensitiven Dotanden R‐811 und beobachteten eine lichtgesteuerte Chiralitätsumkehr des induzierten CLC, der aus dem nematischen Flüssigkristall MLC‐6884 (Merck) hergestellt wurde . Die festgestellte Helixinversion beruht auf dem Zusammenspiel der beiden chiralen Dotanden mit helikalen Twistingkräften entgegengesetzten Vorzeichens im nematischen Wirt.…”
