Photochromism of Fulgides and Related Compounds

Abstract
Steric effect and electronic effect on photochromic properties of fulgides are discussed. A non-destructive readout method using 5-dimethylaminoindolylfulgide is presented. Photochromism of fulgenates and fulgenolides, new classes of thermally irreversible photochromic compounds related to fulgides, are described.
