Abstract

Flavio Romano and francesco Sciortino demonstrated that the realization of a self-assembled kagome lattice from colloids with attractive hydrophobic patches offered a simple and powerful example of the bottom-up design strategy. It was demonstrated that the design of patchy particles that self-assembled into a kagome lattice consisted of spheres whose surfaces were decorated with four small patches, symmetrically located along the equator at alternating intervals of 60° and 120° that they matched the distribution of the four contacts per particle observed in the target lattice. The researchers developed a unique solution to achieve this objective by synthesizing hydrophilic micrometric latex spheres with two opposite polar caps. These polar caps were made hydrophobic through the deposition of self-assembled monolayers of hydrophobic chains, preceded by glancing angle deposition of titanium and gold.
