| Research Abstract |
Photomechanical effects are now widely studied in photochromic materials. This work deals with two-dimensional photomechanical systems that should be of great value to elucidate precise mechanisms at molecular levels. The work composed of three projects. 1) Photoresponsive block copolymers are spread on water and photoinduced morphological changes of two-dimensional microphase separation (MPS) structures are observed. 2) In liquid crystalline (LC) thin films of block copolymers, the orientation of MPS mesostructures are photoaligned and reoriented. The real time observations are feasible by use of an X-ray beam from a synchrotron radiation facility. 3) The precise understandings of transfer motions of LC azobenzene polymers thin films are obtained, and this phenomenon is applied to process inorganic materials.
