Abstract
We study the structure of binary monolayers of large (3 m diameter) very hydrophobic (A) and large (3 m diameter) hydrophilic (B) or small (1 m diameter) hydrophilic (C) silica particles at an octanewater interface. By tuning the composition and packing geometry of the mixed monolayer, we ?nd that a rich variety of two-dimensional hexagonal superlattices of mixed A=B or A=C clusters are formed, stabilized by short-ranged electrostatic induced dipole interactions. The cluster structures obtained are in excellent agreement with zero temperature calculations, indicating that the self-assembly process can be effectively controlled.
