Supramolecular core–shell heterostructures with controllable multi-color-emitting properties

Abstract

A series of supramolecular microscale heterojunctions were constructed <italic>via</italic> a seed-induced solution-epitaxy route and the fabricated multi-layer core–shell architectures possess diverse multi-color-emitting properties. The epitaxial growth mechanism of the growing unit nucleated on the preformed crystalline seed was investigated by the structural analysis of the three constituent crystals and the surface-interface energy balance.
