A series of cycloalkylidene fulgides have been synthesized using β,γ-unsaturated diesters, instead of the usual α,β-unsaturated diesters. A study of their photochromic properties revealed that an increase in the cycloalkylidene ring size caused a subsequent decrease in the formation of the closed form from the open form.
The reaction of carbon monoxide with substituted 2-butyne-1,4-diols by pd(OAc)2/I2 catalyst gives derivatives of dimethylenesuccinic anhydride, “fulgides”, in high yields.

Fulgimide salicylidenaniline derivatives were synthesized and studied in solutions and solid-phase films. It was found that the compounds obtained exhibit photochromic properties in different aggregate states. Comparative studies showed that the nature of substituents in the aldehyde moiety of the fulgimide azomethine fragments has little effect on the photochromic properties of the compounds obtained.
