    • A metal-organic polymer composite structure comprising a microphase-separated structure from a block copolymer composed of two or more polymer chains which are incompatible with each other bonded in an end-to-end manner, wherein one of the polymer phases of said microphase-separated structure selectively contains ultrafine metal particles arranged in a row or rows. A process for producing said metal-organic polymer composite structure, which comprises (i) the step of dissolving “metal ions” and “a block copolymer comprising one or more polymer chains having an affinity for the metal and, bonded thereto in an end-to-end manner, one or more polymer chains having no or little affinity for the metal” in a mixed solvent of “a high-boiling solvent having the ability to reduce the metal ion and having a boiling point of 80 to 200° C.” and “a low-boiling solvent having a boiling point of 10 to 80° C.”; (ii) the step of removing the low-boiling solvent at the boiling point thereof to cause the block copolymer to form a microphase-separated structure; and then (iii) the step of reducing the metal ions while removing the high-boiling solvent at the boiling point thereof.
    • 一种金属 - 有机聚合物复合结构,其包含由两个或更多个彼此不相容的聚合物链组成的嵌段共聚物的微相分离结构,所述聚合物链彼此以端对端方式相互结合,其中所述微相 - 分离结构选择性地包含以行或行排列的超细金属颗粒。 一种制备所述金属 - 有机聚合物复合结构体的方法,其包括(i)溶解“金属离子”和“包含一种或多种对金属具有亲和性的聚合物链的嵌段共聚物的步骤, 在具有降低金属离子并且沸点为80〜200℃的能力的高沸点溶剂的混合溶剂中,对金属没有或几乎没有亲和性的一种或多种聚合物链。 “ 和“沸点为10〜80℃的低沸点溶剂”; (ii)在其沸点下除去低沸点溶剂的步骤,使嵌段共聚物形成微相分离结构; 然后(iii)在其沸点下除去高沸点溶剂的同时还原金属离子的步骤。
