Abstract

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, SC<inf>14</inf>:SSC<inf>10</inf>CHO:SC<inf>2</inf>COOH and SC<inf>18</inf>:SSC<inf>10</inf>CHO:SC<inf>2</inf>COOH, 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.
