| Outline of Final Research Achievements |
We developed functional materials which used pore of nano porous silica having sub nano size. Recent year, research of functional material called carbon-dots have been conducted activity. Carbon-dots have been synthesized by heating of organic compounds as one of the bottom up method. However, this bottom up method have not been optimized. In this study, we first optimized synthetic method by using pore of NPS. When the obtained compound was extracted and refined, it was suggested that this compound was 2-pyron derivative having a structure of cyclic ester. Next, we evaluated physical properties of fluorescent molecules in the pore of NPS. It was found that the molecule can control the aggregation state of fluorescent molecules, because of fluorescent molecules having the same size as the pores can exist as monomolecules in the pores.
