| Research Abstract |
Thermally irreversible stealth photochromic system, which is composed of two colorless states, has been prepared with a short synthetic steps. In addition, a diarylethene which cyclizes photochemically with 100% diastereoselectivity, and a bisthiazolylindenone derivative which cyclizes with high quantum yield, have been synthesized. It has also been showed that the colored form of spirooxazine attached to the cross-linked polysiloxane returns to the stable colorless form with the fast reaction rate as in solution.
