Abstract

in which X is -CR'R", Y is -O- and Z is -CR'R"-; X' is -CR'R", Y' is -O- and Z' is -CR'R"-; A, C, D, F, A', C', D', and F' are H, halogen, alkyl, aryl, alkaryl, aralkyl, alkoxy, hydroxyl, hydroxyalkyl, opt. substd. amino, alkylamino, hydroxyamino, thioalkyl, carboxyl, or siloxy gps. whereby there may be more than one substituent A, C, D, F, A', C', D' and F' on the respective rings; B is H, alkyl or an electron donor gp. such as -OR or -NR2, and E is H, alkyl or an electron acceptor gp. such as -CN, -CHO, -CO-R, or -CO.NHR where R is an opt. substd. hydrocarbon gp.; R' and R" are H, halogen, alkyl or alkoxy. The photoisomers of cpds. (I) and (II) are also claimed. (I) and (II) have photochromic properties and undergo a reversible reacting with the formation of a colourless photoisomer. Prods. are useful for the registration of holograms and for use in reprography, photography and optical memory devices.
