We describe a photodimerization process in organic thin films, for high capacity optical storage in the blue and UV. Neighboring molecules attached through a short peptide chain can be made to undergo cycloaddition. Preliminary experiments performed with anthracene and thymine dipeptides at 360 and 257 nm respectively show that the photo-induced change in absorption is stable both at room temperature, and at elevated temperatures. Very good optical quality films of the monomers can be fabricated.
