Directional Self-Assembly of a Colloidal Metal-Organic Framework

摘要

Materials science is at an early stage of learning to employ anisotropic interaction in self-assembly. One important approach towards this goal involves the study of nm-sized particles, but we note two limitations: first that this is a rather special case as the range of inter-particle interaction in suspensions is typically likewise nm in size, and secondly that the diffraction limit precludes visualizing adjacent nm-sized particles optically at the single-particle level. Among the various nm-sized particles that are known, polyhedra are particularly interesting.
