The quantum yields of the photochromic reaction between (<I>E</I>)- and (<I>Z</I>)-2-[1-(2,5-dimethyl-3-furyl)ethylidene]-3-isopropylidenesuccinic anhydride and the cyclized valence isomer were determined in various solvents and polymers. In both media the ring-opening quantum yield (Φ<SUB>CE</SUB>) depended on the dielectric constant of the media. In some polymer films, Φ<SUB>CE</SUB> were larger, and the cyclization quantum yield (Φ<SUB>EC</SUB>) and olefinic isomerization quantum yields (Φ<SUB>EZ</SUB>) and (Φ<SUB>ZE</SUB>) were smaller than those in the corresponding solvents.
