    摘要: The invention relates to a block copolymer comprising: at least one soft block A with a Tg of between −55° C. and 0° C. and preferably between −40° C. and −1° C., and at least one block B comprising at least one photoactive monomer bearing a photoisomerizable chromophore. The photoactive monomer has the formula (I): in which: X denotes H or CH3—; G denotes —O—C(═O)—, —C(═O)—O—, a substituted or unsubstituted phenyl group, or —NR—C(═O)—, NR being linked to L and R being H or a C1-C10 alkyl group; L denotes a spacer group; CR denotes a photoisomerizable chromophore. The block copolymer makes it possible to obtain a 3D optical memory. The invention also relates to this 3D optical memory.
