| Outline of Final Research Achievements |
The new polymer film that has a chiroptical (circular dichroism and circular polarized luminescence) property was developed by using self-assembled chiral nanostructure. These films exhibit interesting chiroptical properties that can be easily alternated between positive and negative values by thermal treatment. This phenomenon is based on the self-assembly behavior of glutamic acid derivatives.
Moreover, we describe a detail mechanism of the changing chiroptical property by spectroscopic measurement and transmission electron microscopy. To the best of our knowledge, this is the first report of chiral orientation control in the self-assembly of small molecules in a solid polymer matrix. We believe that this method has the potential for producing novel and interesting chiroptical materials.
