Abstract
NEW MATERIAL:A photochromic compound expressed by formula I (R1, R3-R7 are H, halogen, alkyl, allyl, aralkyl, alkoxy, aryloxy, pyryl, furyl, thienyl, amino, cyano, nitro or trifluoromethyl; R2 is cyano, nitro, trifluoromethyl, ester or carbamoyl; X is O or N-R8; R8 is H, alkyl, allyl or aralkyl). EXAMPLE:(E)-alpha-( 5-Cyano-1,2-dimethyl-3-pyrylethylidene )(isopropylidene)succinic anhydride. USE:Capable of providing a colored substance by irradiation with near infrared rays and returning to a colorless substance by irradiation with visible rays and used for optical recording, etc. The absorption wavelength of the colored substance is long and optical reading and writing can be carried out with semi conductor laser. PREPARATION:A succinic acid diester is reacted with a compound expressed by formula II to afford the aimed compound expressed by formula I.
