TL;DR

This paper demonstrates that amphiphilic dendrimers can be used as colloids to experimentally realize a predicted clustering mechanism in soft matter, leading to novel material properties.

Contribution

It shows the potential of amphiphilic dendrimers to realize clustering phenomena predicted in theoretical studies, bridging simulation and experimental possibilities.

Findings

Amphiphilic dendrimers can form clusters at high densities.

Clusters crystallize into cubic lattices with density-independent lattice constants.

The work suggests a new class of materials with unusual properties.

Abstract

Recent theoretical studies have predicted a new clustering mechanism for soft matter particles that interact via a certain kind of purely repulsive, bounded potentials. At sufficiently high densities, clusters of overlapping particles are formed in the fluid, which upon further compression crystallize into cubic lattices with density-independent lattice constants. In this work we show that amphiphilic dendrimers are suitable colloids for the experimental realization of this phenomenon. Thereby, we pave the way for the synthesis of such macromolecules, which form the basis for a novel class of materials with unusual properties.
