Indolinospiropyran compounds and methods for their manufacture |
| abstract |
The present invention provides indolinospiropyran compounds and methods for their manufacture, which compounds are useful as photochromic compounds. The compounds of the invention are substituted on the indole ring with succinimide, which substitution permits ring opening of the succinimide and modulation of the bulk and photochromic properties of the compounds. The compounds may be conveniently prepared using the solid phase organic synthesis of the invention. |
