On the formation of concentric 2D multicomponent assemblies at the solution–solid interface

Abstract

We report on the design and fabrication of a four-component supramolecular network using the ‘core–shell’ approach. Each ‘core’ component templates the formation of an outer ‘shell’ leading to formation of three concentric ‘shells’ around the central guest. The ‘shells’ are formed only in presence of guests thus demonstrating remarkable selectivity in molecular recognition.
