摘要：

Azobenzene-containing liquid crystal polymers (azo-LCPs) with reactive groups attract much attention due to the combined properties of liquid crystallinity, photoresponsivity and reactivity, which make them promising in designing intelligent photo-driven soft actuators. Herein, a post-polymerization modification strategy is used to prepare a series of reactive azo-LCPs using the trans-esterification reaction of poly(pentafluorophenyl acrylate) with functional alcohols. These reactive azo-LCPs show good capabilities in fabricating fibers via a simple thermal-drawing method and subsequent crosslinking reaction with diamine under mild conditions. Furthermore, the prepared fibers exhibit reversible deformation behaviors under the alternate irradiation of UV and visible light (365/530 nm). This facile synthetic strategy is expected to open up new possibilities for fabricating photo-driven actuators.
