Reversible optical rotation change according to the enantiospecific photochromic reaction of [2.2]metacyclophan-1-ene
Chiral [2.2]metacyclophan-1-ene undergoes an enantiospecific photochromic reaction along with a photoreversible optical rotation change at the wavelength where both photoisomers never absorb. This enables us to carry out a non-destructive read-out of the photomemory made by the photochromic [2.2]metacyclophan-1-ene.
