Photo- and thermochromic spiranes 32*. Synthesis and photochromism of 3-methyl-4-oxospiro(2,3-dihydronaphtho-[2,1-e]-1,3-oxazine-2,2'-[2H]-chromenes)
摘要:
Spiropyrans of the naphthoxazinone series have been obtained containing various substituents in the [2H]- chromene portion of the molecule. The spatial structure of a spiropyran containing ortho-positioned hydroxyl and formyl groups was established by X-ray structural analysis. The photochromic properties of the obtained compounds have been studied.
