A~traet--Aberchrome 540 dye is amber in its ring-opened form (A) [(E)-ct-(2,5-dimethyl-3-furylethylidene) (isopropylidene) succinic anhydride]. Irradiation with u.v. (2 > 300 nm) causes the molecules to undergo conrotatory ring-closure and the dye is in its red form (B) [7,7a-dihydro-2,4,7,7,7a-pent
The amber Aberchrome 540 dye [(E) 300 nm) undergoes conrotatory ring-closure to give a red dye (B) [7,7a-dihydro-2,4,7,7,7a-pentamethylbenzo [b] furan-5,6dicarboxylic anhydride]. The red form B may be reversed to form A in the photodecolouration reaction using visible light. The kinetics of the phot
## Ahstract-14berchrome 540 is a photochromic fulgide. It is amber in its ring-opened E-form [(E)-a-(2,5dimethyl-3-furylethylidene) (isopropylidene) succinic anhydride]. Upon irradiation with U.V. light at 1 > 300 nm, the dye undergoes a conrotatory ring closure to give the red C form [7,7a-dihydr
A photochronnc fulgide known as Aberchrome 540 is amber in its ring-opened Z-form [(Z)-a-(2,5-dimethyl-3-furylethylidene) (isopropylidene) succmic anhydrlde]. It is photoisomerized at I > 300 nm to give another ring-opened amber E-form which subsequently undergoes a conrotatory ring closure to give
