| Research Abstract |
We have prepared various types of diarylethene single crystals which exhibit photomechanical effect and revealed that the photoinduced shape changes were controlled by the geometrical structure changes of molecules along with the photoisomerization and the molecular packing mode. In addition, we have also prepared a diarylethene derivative having a perylenebisimide unit and succeeded to reversibly quench the fluorescence by the photoisomerization of the diarylethene unit. The derivative enables us to read the fluorescence signal without destruction.
