摘要
Prior studies using single and binary adsorbates indicate that nanografting impacts the reaction pathways and local structure of self-assembled monolayers （SAMs）. This work explores the influence of nanografting in the case of ternary SAMs. Using atomic force microscopy （AFM） as both a nanografting and imaging tool, the local structures of two ternary SAMs, SC14：SSC10CHO：SC2COOH and SC18：SSC10CHO：SC2COOH, formed under natural growth and nanografting were imaged and compared. The results indicate that nanografting impacts the degree of phase segregation and the domain height in ternary SAMs. In addition to the previously known effect of altering self-assembly pathways, this study reveals an additional impact for these ternary systems： By shaving over the previous trajectory （grafted region）, nanografting could start exchange reactions and lateral movement of surface-bound thiols, which leads to new and somewhat unanticipated local structures.
用单个、二进制的被吸附物质的优先的研究显示 nanografting 影响反应小径和自我装配的单层(SAM ) 的本地结构。这个工作在第三的 SAM 的情况中探索 nanografting 的影响。把原子力量显微镜学(AFM ) 用作 nanografting 和成像工具，二第三的 SAM 的本地结构， SC <sub>14</sub>:SSC<sub>10</sub > CHO : SC <sub>2</sub > COOH 和 SC <sub>18</sub>:SSC<sub>10</sub > CHO : SC <sub>2</sub > COOH，在自然生长下面形成了， nanografting 被想象并且比较。结果显示 nanografting 在第三的 SAM 影响阶段分离和领域高度的度。除了改变的以前已知的效果自己组装小径，这研究为这些第三的系统揭示另外的影响：由在以前的轨道(grafted 区域) 上刮胡子， nanografting 能开始交换反应和表面界限 thiols 的侧面的运动，它导致新、有点未预见到的本地结构。
