The dynamical disorganizing effect of the push-pull azobenzene dye on the liquid crystalline order through its trans-cis-trans photoisomerizaion cycle under visible light was contributed to the efficient phase transition. Then, the effects of light irradiation on the motion of small objects dispersed in the liquid crystals containing the push-pull azobenzene were explored and the manipulation and assembly of those objects were successfully achieved in the nematic phase but also in the smectic phase. The combination of the photo-controlled dynamical change in the liquid crystalline order and the intrinsic self-assembly property of a liquid crystal is promising for use in technologies that require not only the organization of small objects but also the photo-driving of nano- and micro-sized mechanical materials. 2013-07-09 eng journal article VoR http://hdl.handle.net/2298/00046400 https://kumadai.repo.nii.ac.jp/records/34967 https://doi.org/10.1038/srep02167 2045-2322 Scientific Reports 3 1 2167 https://kumadai.repo.nii.ac.jp/record/34967/files/srep02167.pdf application/pdf 1.0 MB
