Article abstract of DOI:10.1246/cl.1987.195

Thin solid films of PMMA doped with donor-acceptor norbornadienes were prepared, and their photochromic properties were examined.The photochromic solid films have absorption at a visible region, and their photochemical decolorization due to valence isomerization proceeded in high quantum yields.They show resistivity for the repeated cycle of the interconversions and no loss in the extinction was observed even after 1E3 times of cycle reactions.
