    • The invention relates to novel monodisperse or polydisperse compounds, in general named DNO (diamino acid N -substituted oligopeptides), preferably low molecular weight polypeptides, e.g., based on ornithine, lysine, diaminobutyric acid, diaminopropionic acid, aminoethylglycine or other amino acids or peptides having azobenzenes or other physically functional groups, e.g., photoresponsive groups, as side chains. These compounds may be synthesised using solid phase peptide synthesis techniques. Materials, e.g. thin films, comprising such compounds may be used for optical storage of information (holographic data storage), nonlinear optics (NLO), as photoconductors, photonic band-gap materials, electrically conducting materials, electroluminescent materials, piezo-electric materials, pyroelectric materials, magnetic materials, ferromagnetic materials, ferroelectric materials, photorefractive materials, or materials in which light-induced conformational changes can be produced. Optical anisotropy may reversibly be generated with polarized laser light whereby a hologram is formed. First order diffraction efficiencies of up to around 80 % have been obtained.
    • 本发明涉及新的单分散或多分散化合物,通常称为DNO(二氨基酸Nα-取代的寡肽),优选低分子量多肽,例如基于鸟氨酸,赖氨酸,二氨基丁酸,二氨基丙酸,氨基乙基甘氨酸或其它氨基 具有偶氮苯或其它物理官能团的酸或肽,例如光响应基团,作为侧链。 这些化合物可以使用固相肽合成技术合成。 材料,例如 包含这些化合物的薄膜可用于信息(全息数据存储),非线性光学(NLO),光电导体,光子带隙材料,导电材料,电致发光材料,压电材料,热电材料, 磁性材料,铁磁材料,铁电材料,光折变材料或可以产生光引起的构象变化的材料。 光学各向异性可以用偏振激光可逆地产生,由此形成全息图。 已获得高达约80%的一级衍射效率。
