| Outline of Final Research Achievements |
This study aimed at the precise synthesis of aqueous functional materials that “connect” the aqueous and non-aqueous interfaces to draw the functions of hydrophobic π-electronic organic materials in aqueous environments. To this end, we started with developing synthetic methods and finding fundamental structures suitable for aqueous functional materials. As a result, new organic functional materials, such as those modulating optical functions in response to water molecules, have been developed. Bioenvironmentally functional polymers with biocompatibility and hydrolyzability by interfacial hydration have been developed, and the relationship between water content and functions has been clarified. New organic laser materials were also developed by hybridizing such polymers and hydrophobic π-conjugated photofunctional molecules. The structure-function relationship based on the control of aggregation of luminescent molecules in aqueous solutions has been also elucidated.
