Abstract
A photomobile polymer fiber containing anthracene carboxylic acid was prepared from a mixture of commercially available compounds and the photomechanical effects of the fiber were investigated. Upon exposure to UV light, the fiber bent toward the actinic light source owing to [4+4] photodimerization of the anthracene unit, which is similar to that for anthracene side-chain polymers. In addition, the photomechanical properties of the fiber were significantly enhanced by the introduction of liquid-crystalline (LC) properties through the addition of low molecular weight LC acids.
