用于光记录材料的金属络合物,制备方法及其制成的光记录染料
摘要：
本发明提供了一种用于光记录材料的金属络合物，由至少一个偶氮化合物及同偶氮化合物配位的金属离子构成，该偶氮化合物具有环状β-双酮结构的重氮成分，以及环状β-双酮结构或吡啶酮结构的偶合剂成分。所述的金属离子优选2价过渡金属。通过在记录层中含有这样的环状β-双酮偶氮化合物的金属络合物，可以得到用短波长的激光进行高密度的光信息记录、读取的光学记录染料，并可用波长350-530nm的激光进行信息的记录。本发明还提供了所述的金属络合物的制备方法和由至少一种所述的金属络合物制备而成的光记录染料。
摘要（英）：

The invention provides a metal complex for optical recording material, which comprises at least one azo compound and metal ions coordinated with the azo compound, wherein the azo compound comprises a diazo component with an annular beta-diketone structure and a coupling agent component with an annular beta-diketone structure or a pyridone structure; and the metal ions are selected preferably from divalent transition metals. When a recording layer contains the metal complex of the annular beta-diketone azo compound, an optical recording dye which records and reads high-density optical information by laser light with short wavelength can be obtained, and the optical recording dye can record information by the laser with the wavelength of 350-530nm. The invention also provides a preparation method of the metal complex and an optical recording dye prepared from at least one metal complex.
