Photoswitching of helical twisting power by chiral diarylethene dopants
Photochromic chiral compounds having two diarylethene units were synthesized in an attempt to use them as dopants for photoresponsive liquid crystals, Stable photoswitching of the photochromic dopants induced large pitch changes of chiral nematic liquid crystals composed of K- 15 and a small amount of the chiral dopants.
