Azobenzene-decorated cellulose nanocrystals as photo-switchable chiral solutes in nematic liquid crystals
Barış Sezgin, Torsten Hegmann
Abstract
Cellulose nanocrystals, surface-decorated with azobenzenes, are introduced as chiral solutes with molecular and morphological chirality and bestowed with the ability to photoswitch the helical pitch of induced chiral nematic liquid crystal phases.
