| Outline of Final Research Achievements |
Organic dyes tend to suffer photochemical or thermal damages although they exhibit excellent optical functions. This problem can be solved by dispersing dye molecules in a polydimethylsiloxane (silicone) rubber, which allows molecules to circulate through its flexible network structure. Damaged molecules are replaced by fresh molecules owing to this circulation, and hence, the lifetime of the optical device is extended. This selfhealing function was demonstrated by repeating coloration-decoloration processes with a photochromic rubber. This rubber also exhibited a smart interconnection that transmitted signals selectively depending on the frequency of pulse occurrence.
