Nanotemplates derived from the self‐assembly of AB‐type block copolymers provide an elegant route to achieve well‐defined metallic dot arrays, even if the variety of pattern symmetries is restricted due to the limited number of structures offered by microphase separated diblock copolymers. A strategy that relies on the use of complex network structures accessible through the self‐assembly of linear ABC‐type terpolymers is presented for the formation of metallic nanodots arrays with “outside‐the‐box” symmetries. Patterned templates formed by the cubic Q214 and orthorhombic O70 network structures are used as excellent platforms to build well‐ordered gold nanodot arrays with unique p3m1 and p2 symmetries, respectively. A simple yet efficient blending strategy is used to tune the critical dimensions of the p3m1 pattern while laterally ordered gold nanodot arrays are also demonstrated through a directed self‐assembly approach. Such highly ordered gold nanodots with tunable particle dimensions and array periods, enabling the control of their plasmonic responses, are attractive probes for biological imaging.

具有独特对称性的金属纳米点图案，从ABC Triblock三元共聚物网络模板化
即使由于微相分离的二嵌段共聚物提供的结构数量有限，图案对称性的多样性受到限制，从AB型嵌段共聚物的自组装衍生的纳米模板仍可提供一种实现明确的金属点阵列的绝妙途径。提出了一种策略，该策略依赖于通过线性ABC型三元共聚物的自组装可访问的复杂网络结构的形成，以形成具有“箱外”对称性的金属纳米点阵列。由立方Q 214和正交O 70网络结构形成的图案化模板用作构建具有唯一p 3 m 1和p的井井有条的金纳米点阵列的绝佳平台分别为2个对称。一种简单而有效的混合策略用于调整p 3 m 1图案的临界尺寸，同时还通过定向自组装方法展示了横向有序的金纳米点阵列。具有可调节的颗粒尺寸和阵列周期的这种高度有序的金纳米点，能够控制其等离子体响应，是用于生物成像的有吸引力的探针。
